    Ola good people, I've been laying low lately more reading than writing so I'll update the new cylinder type and the progress making,so far I've been through 3expansion pipes different confugureations each but now I have one that works well with the set up I'll send picts and so far the performance in this little motor is amazing I've had it hot as **** and still kept pushing the envelope all in all it seems to be working out just fine for the type of loads it goes through so for performance none complaint yet that's for the good and for the bad finding the correct expipe the one I'm using is still not tuned correctly but it runs and for another update last night I got one them steel sleeved lined cylinder from zeda and it is bone stock with a steel sleeve the ports in the cylinder are needing porting and deburring many some cleanup around the everywhere I'll take a couple of snaps I'm not much into conversation rite now so I'll post my questions at a later time but I'll still post the basics for now so far I'm noticing that they didn't do **** to clean the cylinder the sleeve has bigger holes than the actual cylinder so I'll grind off the extra material that's noticeable most definitely its painted black decent job,and it needs dremel work I'm lost for words at the moment pre occupied I'd say so ima take some photos and get my lazy ass to work y'all keep it 100 an I'll do my part the same .....one love motorbikeriders,,,,,,,lewdog

    Yeah you can definitely see the steel lip inside the exhaust port and the transfers need clearing and the skirt can be picked up some hopefully this is the way to go

    i've got picture's as its come along. This is a project i always wanted to do.. full suspension. I found the frame sometime ago just old junk but when i saw it i thought it just might be doable, and it just barely is with a ton of modifications. I've gathered old parts over time, a really good front end and things i've mostly used what i have and whatever i can find. Aftergetting the geometry right i reinforced the rear suspension refurbed a shock and replaced all the bushings. I used a disk ready front then i adapted a disk to the rear, calipers mounted and all of that functional. yesterday i finalized the engine mounting and today im starting on mounting a jack shaft and get all the chains worked out. Other than the motor kit it's been built out of old junk but that was selective junk lol. it's certainly odd looking but done in my own style and i'm real happy with it .

    Sounds good, always intrigued with full suspension builds. Keep in mind the Jackshaft should be as close to the pivot point to keep chain slack to the rear wheel from a-flopping, may need a tensioner...........Curt

    Hi K I was wondering if you can post a picture of the fraim your putting the motor on , I've always wanted to do s full suspension but the configurations have all been like no position for the motor not practical anyway so I'm interested to see how your positioning the motor ok thanks kelly

    Up date: I've noticed a leak from the new cylinder right above the exhaust port it seems that the cylinder has s small tab which has gotten hot enough to open and allow compression to blow through the cooling fins so the other day going through my check list I took a hammer and hammered the open tab back closed ,hear comes the questions now am I losing compression from this pinhole in the cooling fin is this detrimental to the longevity of the little motor and should I jbweld the spot or swap cylinder before it gets worse I half to jbweld cause I'm not skilled in welding aluminum nor brazing I'll try to load some photos anywho y'all got any feedback on this pinhole ima go take some photos I'll be back
