Pull the peacock and clean entire system at this point , start over to alleviate more headaches

Like I said call someone who knows these machines , don't go shaving anything and deg don't take a head to s local machine shop send it to someone that deals with these engines on a regular .

Lol

Need any porting

Everyone has there own method, I put the cylinder in the oven for 20 min then welded it , it could mean the diffrence in the area around the weld cracking or not

I would talk to someone that knows those engines I've run Honda 250r with that static on pump a few times the uccr was still 12:1 with static that high . Bike is together for 6 yrs now running pump . I'm not familiar with suzukis

I have 28 mm pwks I'll do for the crank, not sure if I have cable I'll check

If you can't find anyone by you hit me up

I have fusion welded areas like that before with great success, there's no guarantee it will last forever, I keep in contact with one of them and it's 3 yrs with no problems. The other two I figure no news is good news. While it's not an ideal fix its an option as long as you know the reprocutions

I recently had someone tell me to wrap my hand coned oof in header wrap to keep the heat in pipe it's hard as hell to hear the pipes up enouph after sitting in staging forever then doing the mad dash when they signal the bikes

Ss or 4 mil

17-38, clutch tune will change with gearing changes a lil

Where do you see a bridged ex port? Take a venir caliper and measure the bore, wsm has Pistons and gaskets

Go with zillas suggestion 30 pilot 280 main , if she pulls good read on this site about a plug chop and post pics

If you continue to have problems I'm probably 2 hrs from you , I trouble shoot/ tune/port/build these engines on the regular. Most shops have zero clue how to tune a shee . If I had to put money on it , you have some sort of air leak and electrical issues. Places like that keep my benches full

Take pics of all ports, take measurements in mm from top of deck to top of ports and compare them to cp website

Stock stroke n 4 mill

I also have cranks on hand if you wanna trade , all true n welded with new bearings

Get a lockout , tune base pressure for launch , or have diffrent springs for diffrent riding

Nikasil is a great product, keep up on maintaining top end with compression tests every 20 hrs once compression drops 5-7 psi or differs side to side change rings , my cousins 421 alky cub hasn't been apart in 7 yrs , I've see a 3 lb diffrence in that time

Vitos used to use the 30L rod, u need 795 series wiseco pistons and cut domes. Do yourself a favor and replace the crank seals and inspect crank bearings, you would hate to put a brand new top end together and blow it up because you failed to do proper inspection. Are the cylinders already ported, if not they need to be adjusted for that crank . If your hesitant on doing it pm me

I've put over135 hp on a 520 chain on asphault with no problems , more rotational mass no bueno
