Yamaha IT175J Piston Wanted
« on: October 11, 2019, 03:54:40 PM »
Hi, anybody got a 4th or 5th over size ( 1mm or 1.25mm) piston they would like to sell or a source. Big end failure just wrecked my genuine 5X8 3rd o/s piston recently installed ????????. Can't find anything on eBay or in dealer stocks around the country. Nothing avail Prox under 1.75mm and don't want to go that far and use up all remaining bore.
My only other option seems to be repin another model piston, possibly a 2N5/2A7 or a 3R6, has anybody done this and has positive or negative outcome.
Or has anybody got any other ideas/options, seems to be an issue that many could be facing unless they already have back up Pistons
Many thanks any comments/advice.
Regards

Thanks viper666 got your pm. Fortunately with help from a FB site user have been able to locate a 4th o/s genuine 5x8 piston from USA, it's on it's way now so all going well immediate problem solved. Have already got the Prox 1.75 as a back up and I know they are OK for this model but just didn't want to bore it that far out right now and lose the 1mm of remaining bore. As far as the other 1.5 o/s listed from uk from my investigations I think they may be a Chinese piston rebranded and have read somewhere about poss not suiting the J/K models, but not sure so as you say pretty cheap may be worth a look at as another back up, unless anybody on here has used and can give a comment, that would be a great assist.
Thanks and regards
