shercojon Posted May 28, 2016 Report Share Posted May 28, 2016 Hello, I've recently bought a Sherco 290 and I'm concerned at the noise the engine makes.I'm new to Trials and 2 strokes, can someone please tell me if this is how they're supposed to sound? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
trialsguy8 Posted May 28, 2016 Report Share Posted May 28, 2016 Not sure about the noise but that paint job on the tank looks good! Quote Link to comment Share on other sites More sharing options...
tony27 Posted May 28, 2016 Report Share Posted May 28, 2016 No that's not how it should sound. I was expecting to hear rumbling main bearings but that sounds more ominous, I'm picking it was put away with some water sitting in the motor or airbox at some stage Quote Link to comment Share on other sites More sharing options...
shercojon Posted May 28, 2016 Author Report Share Posted May 28, 2016 Personally i think its a worn top end bearing, but i might be wrong. parts ordered, so time will tell. Quote Link to comment Share on other sites More sharing options...
rob214 Posted May 28, 2016 Report Share Posted May 28, 2016 does it sound that way while riding? take it off the metal stand and see if t heres a difference. i didn't hear anything you might be hearing from that video. you do have oil in the gas ? properly ?

zerorev3rev4 Posted May 28, 2016 Report Share Posted May 28, 2016 You got piston slap mate check clearance an oversize piston could cure it Quote Link to comment Share on other sites More sharing options...
copemech Posted May 31, 2016 Report Share Posted May 31, 2016 Sounds like a stock Sherco of the year. Has some wear, naturally. Just ride it. Barring things changing this is a non issue. 2 Quote Link to comment Share on other sites More sharing options...
fxstbi Posted June 1, 2016 Report Share Posted June 1, 2016 I agree with cope. My '13 250 sounded like that for two years, I sold it to a friend and it still sounds like that. Ride it! Quote Link to comment Share on other sites More sharing options...
shercojon Posted June 1, 2016 Author Report Share Posted June 1, 2016 Thanks guys, I couldn't live with it. With a little motivation from my son, 'Get on with it' I stripped it. There was piston slap, and on closer inspection found the barrel was scored and had sustained damage. Best option new piston and reconditioned barrel from Trials and off roader's, £299. Posted mine off and waiting return. Message to buyers, be careful what you buy and who you buy from. Not all sellers are honest. Quote Link to comment Share on other sites More sharing options...
heffergm Posted June 1, 2016 Report Share Posted June 1, 2016 Unless you were told that the barrel and piston were new (which obviously they weren't) what information were you given that makes you suspect dishonesty? Plenty of people aren't mechanics and aren't going to be able to tell a buyer with any certainty the condition of the motor internals (and even the ones that are good mechanics probably aren't in there poking around often enough to say so either).

shercojon Posted June 18, 2016 Author Report Share Posted June 18, 2016 Piston and cylinder arrived, together with gudgeon pin,clips, gasket set, small end bearing and all for £300 plus £10 P&P. next dat delivery,Thanks to Tony @ Road&Trials (01226391557) Went together very easily and i'm no expert. ' Cover the engine with a rag when fitting the gudgeon pins or they'll be lost forever'. Couldn't torque to settings as my wrench wouldn't go so low, so used good old 'feel'. Fired up 2nd kick. Sounds and goes right now. Took about 2 hours including coffee break. Job done. 1 Quote Link to comment Share on other sites More sharing options...
