Clear and simple valve adjustment, actually my first time trying it myself. engine ran very quiet and smooth afterward! (all that editing actually takes allot of time for clips like this) music by: IKSON
I cut and pasted some info for you from the Rincon Forum regarding the cam chain tensioner trick. My 06 did this and was rattling something fierce. Was a easy fix to put more tension on the tensioner and it fixed the problem. If you still have engine noise after your valve adjustment then the cam chain is probably the culprit. Cheers.
Cam chain tensioner repair Do any of you have the "rattle"? There have been several threads over the years about replacing the OEM cam chain tensioner (cct) with aftermarket manual type (no spring). This is a fine method but I wanted to fix the stock one. This is done to eliminate the rattle that shows up in the Rincon. The rattle is worse when cold and goes away when hot…eventually it will not go away. The rattle is your cam chain whipping around due to inadequate tension and will wear out the chain more quickly than a properly tensioned one. There are several threads relating to parts of this issue and repair, so some of what I suggest is not my original thinking. Here goes. The stock cct uses a spring loaded ratchet that extends as the chain wears. This is the issue. The ratchet has 4 revolutions from full in to full out. When the chain is new, the cct does not extend much and the spring is tight. As the chain wears, the ratchet goes further out and the spring unwinds thus having less force available. Somebody posted once that they tightened the spring but had no more details how they did it. On my atv the OEM cct started to rattle at 7500 or so miles and I just replaced it. Problem solved for a while. Then lately at 11,300 miles the rattle returned. I was going to put a manual cct in but did not want to always wonder does it need to be adjusted or not (and I am cheap). So I removed my cct to have a look. Sure enough, on my bike the cct is currently at 3 revolutions out and I only have a little more travel left (1 revolution). The remaining spring tension in the cct was not enough to extend the ratchet any further. I had a spare cct from the first change. I disassembled it to see how to tighten the spring. Here is the best description I can give. · Remove the retaining circlip with the plunger held by a finger so it does not pop out of the cct body. · Let the interior mechanism come out until the circlip groove is just above the cct body still holding plunger with finger. · Use installation key or screw driver and add 2 to 3 “extra” full twists (complete 360 revolutions) to spring. I would not add more spring tension than this as the spring would have unwound the amount I am rewinding it. · Then push plunger back inside cct body until circlip can be reinstalled. · This seems complicated and took me a few hours to figure out it could be done without fully disassembling the cct. · The difference in force the cct applies after fixing is very noticeable. I reinstalled the cct and my bike is now purring again when cold at start up. When it starts to rattle again, I likely will need a new cam chain. I had pictures but they were not good enough to show what I was doing...sorry. I will check in on thread if anybody has questions or comments about my repair. Happy motoring. Rattle free again in Kentucky.
Lucky Goose very helpful info but if u saw my earlier vids you also saw how stretched out my actual cam chain was that i replaced immediately! (cam or timing chain same thing right?)
denis gorelyy oh good that you replaced it. That cam chain tensioner trick is just to put a bit more pre load on the slider. The tensioner seems to stick sometimes and stops ratcheting out to keep tension on the chain. Have fun replacing the front bushings. Will be a great result.
Thanks from a new old Rincon owner. (2003) Within a few miles from purchase, It went from from runung great to no power. No apparent noise like ticking. After i do the easy stuff- oil change , plug , it sounds like a bad cam shaft could be the culprit. is there a measurement of valve stroke that could easily determine whether the lobes are worn or shot. your vid i estimated about 1/2 in of movement. thanks!
Heather Medcalf oh yes i just got a box full of new parts this week to replace all the rear bushings and sloppy rear a-arm components! (and ive already got the front ones all replaced:) nice and tight now!
I've got one that's been sitting for about four years. I cleaned the carburetor and the gas tank and replaced the spark plug and it still won't start it just backfires thought the exhaust. Any suggestions ?
