Ok guys, I'm new to trx250r scene. Just picked up my first 1988 250r. Based off what previous owner told me, the bike runs on 50/50 VP 110 and 91 and has the following mods, has no air box, running a fmf pipe, bike had a Pj 38mm Keihin. When I purchased the bike I was having constant trouble starting it. I decided to put in a 38mm airstriker I had laying around from another bike. I also tested compression and got 190psi. I'm running castor 927 at 32:1 and still using 50/50 vp 110 and 91 fuel. When I took off the old PJ 38mm it had a 160 main and a 62 pilot. Once the bike was started it ran great but engine felt more hot than usual. I now put the new airstricker 38mm and bike starts in 1-2 kicks. However I need help with jetting. Im at sea level and ride majority of the time a pismo beach. Another issue that I have noticed is since changing carbs the bike has now began to leak oil where the pipe meets the exhaust flange. It never leaked before up until I changed the carb's out. I have attached pictures of the bike. Any help with recommendations and jetting is greatly appreciated. thumb_IMG_9093_1024.jpg thumb_IMG_9086_1024.jpg thumb_IMG_9094_1024.jpg thumb_IMG_9092_1024.jpg thumb_IMG_9091_1024.jpg

imo the pilot is way too large.should be more in the 45-48 range.main seems a touch small but possable.as for the pipe.pull off clean and put some hondabond on the flange and re install or buy a 3oring aftermarket flange.i still use hondabond on those also.
