Wanted / 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

Yamaha / IT 175J intake manifold

« on: July 14, 2019, 03:19:16 PM »

Hi all
Just after some ideas or recommendations re ongoing problems with Yamaha IT175J intake manifold. Original was very cracked (appeared to be on outside only) so to be on safe side decided to replace with the current repro items. First one purchased had flaws/leaks in rubber to metal bond plus the rubber body itself, unnoticed at first, which possibly part contributed to a major engine failure, second one has just shown the same flaws after only 6 or so rides and with possibility of air leaks I have removed. Now I am back to resurrecting the original item which I have heavily coated on the outside with sikaflex sealant in the hope of sealing or preventing any possible air leaks. This I am hoping will be a suitable fix for next weekend ride, not sure if this will be a long term fix. Am reluctant to get a third repro item as quality seems very poor and they ain't cheap, am guessing this may be a problem for others so any current ideas other than the above (all searches only lead me to very old posts/info) can another model be adapted (don't know if this will solve the quality problem though), is there something else available (I only seem to be able to find the one USA source avail of the repro item - postage is mind blowing) and J model item seems very rare. Any ideas appreciated.
