125-200cc Found another use for wr165

Man is it fun and bike ran great just needed to richen needle 1/4 turn and main jet also I take from extra load from great traction rode down the river to lake 5 miles.

Who made your swingarm stickers?

What no spark arrestor?

Pg graphics made it. Do not need spark arrester where I ride 90% of the time. But should get one anyways, any recomdations for spark arrester. Wallybean I took compression test after 1 hour break in and was at 195psi just took one yesterday and now at 200psi after 45-50 hours I figure it would be less and was using same gauge. So may as well just leave it for another year of riding.

The hydraulic fracking that Walts favorite president has allowed to reduce our fuel cost to a tolerable level might make that ice flammable! :-)

lol a spark arrestor is a joke . dont bother .

You get caught riding in national/state forest without one and it won't be so funny. Might be a joke in NZ, not in the US. I have had Rangers check mine. Once they saw the USFS approved, they were all nice.

FMF makes a good one and the label is stamped into the aluminum vice a sticker.

I was joking considering when/where you are riding. I also knew that you didn't need one for most of your riding. If you do get one the FMF TCII is what I use and I like them. Easy to work on and fit well. Spark arrestor is no joking matter when riding on Govt. land here. It is usually the second thing we get checked on after our OHV sticker. Thankfully I don't see a FS cop but once every other year or so.

i really dont need the spark arrestor either but i installed a dynoport unit on my 360. the bike sounds excellent with it and its somewhat quiet if you are easy on it. start putting it under a load and it gets loud but most of the noise comes from the airbox. unlike my younger years, i have been trying to keep things somewhat quieter than i used to. dynoport uses the spiral style arrestor. i dont feel they hurt power too bad.

Is a 2stroke even capable of backfiring a spark?

probably not likely

well they are probably are needed then in certain climate. i just like how they are a bit quieter. here in pa its never dry all that long

Was riding with a guy on ktm 125 sx on road sections he thrashed it so hard trying to keep up his exhaust packing was burning out of the back, so yes fire 2 stroke highly likly.

Probably not but if your jetting is off and it eats the piston it could. I used to do a lot of car racing, both oval and drag. I've seen lots of red hot things fly out of the tail pipes of engines while racing at night.
