March 1, 20188 yr Sherco 290 My cylinder is off to get replated. The conrod kit at £210 looks pricey if the conrod is ok. There is play at the big end, how would I know if the conrod is OK to reuse? thanks
March 1, 20188 yr Wot he said. While it's stripped down that far do a good job and you shouldn't need to repeat again for years.
March 1, 20188 yr Seems the sensible route to buy the rod kit despite the cost. Many moons ago I had a Suzuki AC50, rare thing even then. That needed a big end change, and because the bearing was obsolete the company who rebuilt the crank bored out the rod to accept a slightly larger OD bearing. I would only consider this if parts were not available, and the value/risk was low. TBH never felt 100% happy about it, but had no choice. So vote for me is the rod kit route
March 1, 20188 yr Cos I've got too much time on my hands tonight, found this, might save a few quid. Have never used the company and not 100% sure it's the right one, but maybe worth a look. Using XE.com this rod kits is £164 plus del. Looks like some kind of dealer clearance of Sherco parts? https://shercodiscountparts.com/collections/sherco-trials/products/conrod-kit-2-5-2-9-r021
March 1, 20188 yr What oni nou said, you need the con-rod, pin and bearing. Any wear on the big end usually affects the con-rod bearing surface, the pin and the rollers. Either your bike is really old, has had a lack of oil or has been drowned in water which has settled for a while for the big end to wear, not the norm on later day bikes for big ends wearing out. Bye, Peter B.

Saved over $200 on the stator for my bike as opposed to getting it from my local dealer. That company is in Canada so shipping might be higher than what you might expect.

March 2, 20188 yr Author I don't think there was contact with the head, it looks fine. The piston is scored and the cylinder has a wee mark.`

You jest but, decades ago, a pal put the bottom half of his Yamaha racing motor below the bed for winter storage. The evident rust come springtime was due to the cat having "used" the crankcase. When he told us this I don't think he realised what it said about the state of his room that he hadn't noticed the smell when it happened.
March 11, 20188 yr Author Googling may not work for this one, "We dont do Sherco" is the reply from 3 businesses so far.
