I remember reading on here about a 190 piston in a TV barrel conversion, but for the life of me cannot find the thread. What I was reading must have been buried in another thread. Anyone know where in the hell the 190 Wiseco piston thread is?
That's not going anywhere...

My barrel is a TV2 Suzuki 190 conversion, with RD400 rod.

Mine isn't related to the thread you mentioned though I don't think; so not sure if I can offer you any help. Also I think my piston is Mitaka not Wiseco. But PM if I can help at all.

Cheers Stu.

Rude de ...........what make are the pistons that Allstyles sell?
Thing is, the WHOLE point of any Jap conversion, and why they became popular in the first place IS using the stronger more reliable piston and rings. Thats why you often have to split cranks, change rods etc - its all about making the piston fit . The end result is building a more reliable engine using the best that is available.
If you are lucky you may find some NOS TS 185 Suzuki pistons around, esp ebay. The Mitaka is a very good Suzi pattern, but as you are probably aware the Wiseco is top quality (but more expensive). I know the German guys rave about Wossner pistons but not sure if they are available in 64 + mm with the correct crown height, peg positions etc?
Then the scope for further tuning is improved, alllowing you to open up the ports especially the exhaust to sizes that the previously available piston / rings found dificult to cope with.

That's the one I believe. Using a TV rod. 2mm base packer required?
Thanks Lads
Rude De, I'm not boring a TV barrel out to 200, unless I absolutly have to. Thin cylinder walls are not your friend. Get back over to the other place :moon: :)

I still can't find that thread though :cry:

Briliant, thank you Jims.
Customer is running just a stock 20mm carb and a big bore, nothing to fancy. He just wants reliablilty. Haven't been able to find an 62.8 piston, which is what we need and would prefer.
Is it really going to be worth the time and money to start messing with shortening when using the TV rod? I thought it would be a straight drop in, with perhaps a little packing on the bottom.
It is an original(OG as they say here) cylinder and I do have a 175 head that appears to have more room in it than the others. Of course, all ports will be smoothed and matched.
Sorry for wasting so much time on such a simple conversion...

So 39-34=5mm deck difference
116-107=9mm rod difference
9-5=4mm size of packer to make it a drop in?
Really not looking for a road screaming beasty here. Don't think there will be a need for transformation. I'm thinking there'll be a little work to be done with the skirts, which is not a prob.
Rude De, where are you? Don't be shy :ninja:
Once again, I thank you Jims
