Little Suzuki TS90 and TC90 dirt bike engines had disk valves. I bought the racing one and built a 20,000 rpm expansion chamber for it. A guy owned a dirt bike shop told us to fit a Hodaka 100 piston to it and then cut off the top of the cylinder. That gave it lots of port time area. Good times. The only thing I know about Bighorns is an article I read about guys road racing them against 350cc twins and giving a fair account of themselves. But "all other things being equal" the 350 single's mechanical integrity redline is lower than a twin's.
So cool my first ever bike was a ts90 when I was 7 - I loved that bike! 20'000 rpm sounds crazy. This motor is to be used for vintage motocross and is in a very cool Boyd & Stellings frame very rare and very cool
I have just cleaned my uncles rayburn and there's a steel pipe about 10cm long going from the copper pipe to the middle of the of the burner with a hole through it around 8mm big. Going by what you have done with a 3.5mm drill bit does it mean this short piece of steel pipe has much to bigga bore through it?
@@thundertiger76 no problem - there will obviously be a difference - maybe the flow is controlled by a smaller jet near the burner? Anyway check it out next time
@@phoenixmotos9712 No jet as such, the exit hole for the oil is nearly as big. I assume it fills up the cup like shape well until it flows through the channels to the wicks?
Hi!! Out of curiosity what would you charge to come out and clean one of these ovens. Buying a house in Peterborough that has one but with seven ovens I believe (really big ones) and it is oil.
Ah sorry I just did this video for a friend who was thinking about offering this as a service in his business. I think it's probably about £200 for someone to come and do it
my first bike was a 79 RM50, i rode it through a fence 30mins after my brother showed me how to ride it, 2 weeks later my brother had his middle left finger chopped off when he fell of and put his hand in the rear sprocket. my parents banned me from having motorbikes for a few years after that. #good times.
How’s this project going I thinking about getting a 88 kx250 but it has not compression and would need to clean carbs. Was it difficult finding parts in from the US
My high school friend had one, white/yellow. We were riding one summer day in a hay field, he took a dump after hitting a tractor tire rut, the hot exhaust caught the hay field on fire and burned up his bike and several acres of prime hay. Was a bad day!!
That tank is the enduro version.. when I bought my 91 540 I had a choice of MX tank with Radiator shrouds or the bigger that you have .. I think the difference was 9.5 to 14ltr ..I’m glad I picked the big one 😎🇦🇺👍🏼
@@phoenixmotos9712 I've tested a few 250 Hondas to destruction on Mablethorpe beach 😁- they seem to have a weak spot between the plug and the exhaust valves. I'd always try to spot it when rummaging eBay for a replacement head. Hope your rebuild goes well 👍
Yamaha were funny in Europe yz's we're white, us were yellow suzuki also yellow so I think to differentiate themselves they chose a colour that nobody else was really using - stuck with yellow in 90s and then switched to blue
I raced one of those in 1982. That honestly looks like a pretty low hours bike, looks like original tank and side cover graphics and stock silencer. Funnily enough, my younger brother raced an ‘83 CR 60 back then, too.
Raced this bike in Australia doing mainly enduros and the occasional motor cross event. Great bike but very little rear brakes in the mud. Love to get another to restore to original for my grandson. 2 stroke screamer
