Hello! Apparently I'm the only one here But welcome anyway!

I don't know much about the G, but here is a wire diagram for the S



Make sure the kill switch is in the on position.
Make sure you have a good spark plug. Try swapping another plug.
The most probable cause is a wire is disconnected or grounded when it shouldn't be. I'd inspect all the wiring for obvious trouble.

 

Im here HEHE

 

Matt did you get spark yet no that 230cc??

 

Cool! The more the merrier!

 

Hi, Toaster556/500XC here. I build mostly first gen Suzuki DR125s, but I've picked up an 86 Suzuki DR200 to build for more hardcore trail riding, and Im building a big bore motor for it. For those who are unaware and wondering WTF this n00b is doing posting about a dirt bike, the DR200 and LT230 share a piston, with the DR200 having valve reliefs and the 230 having none.
Since no one makes a big bore piston for the DR200 and I want a lighter piston than the boat anchor Wiseco 70mm 230 big bore, Im gathering people for a group buy of custom Venolia 69mm 11:1 pistons at a cost of $115 ea for a bare piston. With Wiseco rings, OE Suzuki pin and circlips, it will be under $190 plus shipping.
Is there any interest here? It would bring a 230 up to 250, and keep compression around 10.5:1 with a 230S or 250S head

 

A 230s owner would have to resleeve too, right?

Yeah, Wiseco is a boat anchor. One would think there would be a bike piston with a 16mm pin off the shelf.

 

I just mic'd my LT230 cylinder's sleevem and at 72 mm (71.9582) it would be VERY close if someone chose not to resleeve. I run a 1.5mm sleeve on my DR190, and have for the past nearly 5 years with no problems, so I would personally run it. I won't tell anyone what to do with their engine (besides get in on this group buy!) however.

There's one piston that would work for a 70 mm big bore, but it's another boat anchor. Yamaha YTM/YFM/ TTR/ XT225 had the right pin height, but very little dome, so pair it with a 185 head for decent compression.

 

If the piston is a little taller, shim the jug up higher and get a longer cam chain. Having a longer piston would be more reliable with the weak rod those engines have anyway.

The 250s version has a 17mm rod and the KZ1000 pistons fit it. Some of those pistons are tall. Apparently there were two version of the KZ1000 (or maybe it was the 900 that was different.) Anyway, I think I could go all the way up to 74 or 76 or something crazy like that. I'm curious if the 230's 16mm rod has a similar selection of pistons from streetbikes. With all the 1000s and 1000s of pistons made, you'd think something would work.

I'll have to take your word for the resleeving. The guy at KustomKraft told me they had to be resleeved for the big bore kit he sold. Maybe he was trying to sell his services, idk. The bore may warp if it's too thin. 1985-1989 LT 230-260cc Big Bore Kit. | KUSTOM - KRAFT PERFORMANCE

But if you're willing to resleeve anyway, it's a better deal to get the piston you have in mind rather than the boat anchor from KustomKraft.

I shaved off some, but it didn't amount to much. Maybe 5 grams if I remember right.

 

Matt did you get spark yet on that 230cc??
