This channel is a place were I document and share my vintage motorcycle and automotive endeavors. Which mostly includes Norton, Triumph, & Harley Davidson motorcycles. This channel contains videos on procedures of restoration and maintenance and includes history and recreation as well.
Yes those are breathers in an earlier video we talked about those breathers and we found those quite reasonably priced they made sense to us to add. Those aluminum washers are a necessity, Here is the video when we first installed the rocker boxes ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-93-HtxggcE0.htmlsi=-XEQjzX9qzy2vr72 hopefully this helps, in the comments in that video there is a link for the rocker box breathers on where to find the ones we got,
The 1970 onwards the triumphs have a 3124 cam on inlet and exhaust. Unlike the original preunit Bonnie which had a 3124 inlet and 3325 exhaust cam. When you set the cams to T120 seting the inlet cam one tooth advanced that advances the cam 13degrees ahead and increases the exhaust -inlet valve overlap which is fine when the 3325 exhaust cam is used. So the not TR6/T120 setting is better and is hence making more power and torque in the blue bike. To rectify the Bonnie you need to use the vernier cam centers and time the Bonnie with 105 degrees exhaust lobe centres and then the bike will perform. My information of the cams comes from triumph twins by Roy bacon and I follow Mr Pete (Rip)on Brit bike forum 🙏🏻
@@user-ek5hp4fn4l We choose to stay with the same style bearings as original. Although sealed bearings would've probably worked fine, but we didn't want that style.
In 5 minutes, I'm gonna put the head and rocker boxes back on my 1974 Trident. Took everything off to seal some oil leaks like you guys did. Seems that someone forgot to put the aluminun crush washers under the 6 allen head rocker box screws? It appears to me that where the "inspection caps" are in the back of the rocker boxes, on both, intake and exhaust boxes you added a hexagon plug with hose coming out of the hexagon bolt??? Is this a breather you added for the intake and exhaust rocker boxes??? My friend, Brandon at Steadfast Cycles told me that all Tridents are prone to leaky rocker boxes and you will NEVER solve the leaky rocker boxes UNLESS to add a breather to each rocker box???? Is that what you did???

This brings back memories! About 6 months ago I was rebuilding the forks on my '69 Tiger I am restoring. Not too bad of a job to do, but like everything on these bikes there is an order of operations, everything goes together in a sequence. As for the different thread types, just remember, cross threads is better than no threads ;)
AH Americans are confused, by something that isn't designed for monkeys. C'Mon. Doya think that keeping the printing face up might have been a hint and IF you oiled them they 'may' have gone back together easier , just a thought. FYI I think it its a crappy design.
I need the washer and the hex nut that you used to attach the arm to the cam. I have a 57 pan . Where can I order them? They are missing. Thank you. Ricardo
It looks like you are looking for old number 0129 and 0261 the print says 0262 but that washer is really difficult to locate and I believe the later parts books say 0261 the new numbers are 7789 and 7050 a good place to find individual hardware parts is Deluxe HD restorations, deluxehdrestorations.com/search?x=0&y=0&q=3%2F8 just click on the menu and click on the search and type in the individual hardware part numbers I get a lot of my hardware here and colony hardware kits are great, good luck and thanks
Just came from the garage and trying to install my front fender the exact style of yours. Now that I know it really is a pain in the balls I can go back and finish. Thank you guys.
Speaking as a collector of guhns, cold blue doesn't stop rust. It's just copper selenide. I can rub it off with a "Miracle Cloth." Cadmium plate might be more of what you're looking for.
Thanks for the video. Im about to tackle my first clutch on my 78 Bonneville. I was just going to do plates but I might do the rubbers after watching your video.
The air screws can be anywhere from 1.5 to 2.5 turns out on Amal Mk2 carburetors it generally relates to the pilot jet size. We have number 25 pilot jets and air screws are approximately 2 turns out. Turning the air screw in for rich and out leans it. So if your engine gets it's highest running with the air screws less than 1.5 turns you need a bigger pilot jet if the highest idle is over 2.5 turns you need a smaller pilot jet it should idle well at 1000 rpm at around 2 turns out also sometimes popping can occur on the over run while decelerating is caused by leaness so turning the air screws in by an 1/8 to 1/4 turn usually clears that up. All 78 and later T140E with parallel ported heads with Mk2 carburetors need a hotter plug or fouling occurs. RN5C champion or BR6ES NGK plugs are the correct size you don't need the R plugs but it's getting hard to find non resistor spark plugs and R plugs work just fine.
hi i have just acquired 1979 T140E with mkii carbs US jetting bike runs/starts great but has slight stumble off idle did you change just the needle jet to 106? did that help? thanks for any info
Yes for our bike the 106 mk2 needle jet works very well different elevations might need different needle height adjustments but all the other jets and needle are standard. I tried the so called Non EPA needle and parts but I couldn't get it to run near as good as it does now.
@@jessesvintagegarage765 many thanks for the info my bike is street tracker style built from basketcase with mostly new parts including new mkiis can i post a pic here?
Great video. Now I know about using a long screw driver from the top to hold the damper in place while getting the allen bolt out of the bottom. I was shouting at you guys to pull the handle bars off the bike in order to get those little spacers in p-clamps. The bar weren't even bolted on. Take them to the bench and bang the shim/spacers in place with a drift if needed, or move p-clamps around... THEN put the bars onto the bike. You guys know way more than I do about motorcycles, but that method seems way harder than it should have been. : )
Yes when motor was up to operating temperature the oil pressure before the change ran between 32 and 35lbs now after the change it starts cold at 60lbs and after it get fully up to operating temperature it's running at 50lbs these pressures I'm referring to are at cruising speed at around 60 of course at lower speeds it's lower pressures.
I'm building a t120 bonny . ive timed the gears with the marks as you've shown. Having a problem w intake valves hitting the piston. Valves are opening while pistons are coming up. Can u please give me some advice on this issue.
@@jessesvintagegarage765 Thank you for the details. I have been thinking about putting together a new ratchet top using a VT case and US sourced internals like you have here. However I have not seen many folks use a VT case. Would you use their case again?
@@QuiltingJeri sure would in fact I needed a second transmission case for my 56 pan and got the same part for that bike, this transmission case is excellent and the parts went right in and worked as you can see in this video, but I am working on a new video on the 40 and I have rode it a couple times and the transmission functions great as well,
Well, kick starting a bike with the kick stand down is fine if you aren't standing on the rider pegs and kicking, putting all your weight and the bikes weight on the side stand while kicking! I always hold the bike while standing on the ground and kick. To me, the side stand is down for a safety measure against having the bike accidentally falling over while kicking.
I was always told that copper gaskets have to be annealed (by heating them and then quenching them in cold water) so they will be soft enough to form to the mating surfaces. Do you have some reason for not doing this on the rocker box gaskets? Or is this only necessary for the Head gasket? I’m surprised you had those other gaskets fall apart like that. Definitely not satisfactory in my book! I’m currently rebuilding a 1974 Trident top end for a friend of mine after having the head refurbished with new guides, Black Diamond valves, exhaust ports worked, new rings on the standard pistons, honing the bore, etc. The head was in a sorry state, but the pistons and bores are well within tolerance. I watched you installing the rockers on this bike a while back and I noticed you didn't seem to follow the tightening sequence. Possibly this is a factor in your leakage woes?
Your issue with the Bonneville could be the balance between the carbies. I had a 1974 750 Bonnie and later a Tiger 750, which seemed to run a lot smoother than the Bonnie and I believe that was due to the balance between the carbs being ‘off’. I owned two tridents, a 1969 T150 and a 1975 T160 and I have a soft spot for them. They were and are very special machines, that sound like no other motorcycle, ever.
I was always taught that we should tighten the screws in a cross pattern, where your second bolt is diagonally opposite the first, then back and forth as you work your way around. I guess that’s not so important with only tightening each bolt one turn at a time?
Well the guy that my father was helping years ago at the Triumph dealership showed and taught him the same way that we did this clutch, he had told him it was best way not to warp anything taking it apart or putting it back together when it came to clutches like these.
I know this is old but you are solving a problem I did not know. I am replacing the clutch on my 1973 Norton. I noticed oil on the plates and hardly any trans oil. Thanks for the time and effort you have put in you videos. Its helping some one out there. To day thats me.
Gorgeous resto. Got a '73 Roadster, myself. I installed the CNW reed valve breather, and it made a surprising performance improvement. But, I was hoping you could mention the source for that little plastic fairing.
The fairing well I bought that around ten years ago but I was able to find it again on eBay I would give you the auction number but it will end up not working someday for future people wanting to know, so the following is the description of the fairing and a google search can find it, ( UNIVERSAL CAFE RACER BIKINI FRONT HEADLIGHT FAIRING FLYSCREEN WINDSCREEN 8" ) good luck it turned out great for me. Thanks for the great comment,
Thanks for the video. Ill be referring to it shortly when I do my own rebuild. Is there a reason why the barrel and cylinder head cant be installed while the engine is on the bench and then dropped into the bike? I would think it would be easier, no?
Well that depends on how much help you have, and keep in mind that motor is very heavy and the motor mounts move around so we find it's way easier the way we done it in this video. Thanks for the great comment,
I also have a '72 Commando (Roadster, Combat).Thanks for all the details on this video. The video is a great motivator for me to get back to working on the bike. Right now it's just eye candy. 🙂I need to pull the engine and make all of these updates as I don't know what prior work was done on it. I've been planning to add the Jim Schmidt upgrades when I do that. Special thanks to everyone's comments here. Super valuable.
Thanks for asking well some things got in front of it and we’re going to get back to working on it really soon, I just got the frame back from getting painted a couple months ago and in the hopefully soon future we will start working on the case and over the next few months we will start assembling it and I feel it will be a fun project thanks for letting me know someone is interested in seeing it get back together other than us,
Like I said in a previous post I just had my brothers 1971 triumph tiger restored and I am not at all familiar with this bike I am a Harley rider but these videos help tremendously thank you so much … how can I send you pictures of the restoration ?
