Yeah wasn't to happy to mess with them for 5 hoursThey look really nice, but I would be screwed if I got them and had that issue, I can’t fabricate.
You did a great job on the mounts and it looks awesome.
Just a front caliper bolt hahaNice that you finally got some seat time on that beauty. How did she hold up, anything loosen up on you?
Yup you’re probably right I might just throw the stock carb on and see how it feels I’d expect to gain more bottom but I’m doubting as much as I want. I’m used to my ktm 300 power and that’s what I’m expecting from a 350 build so we will see. But I also just sent my shocks back out too.You have a 38mm carb right? If so that may be a little too much carb for good bottom on a quad without a big bore. Compression makes a big difference in power but it doesn't demand any larger of a carburetor. 250 dirt bikes all come stock with 38s but they don't need the bottom that a quad does. That's probably why you gotta scream it. You might go down to a 36 before your other engines get done especially if there is going to be a wait.
yeah somebody did make the boosters bigger and knife edged the transfers. I’m assuming they took too much material out hurting my low end. I could send out a stock cylinder I have to have a piston fited but I will see. Lack of torque is so bad at lower rpm that when I climbed a pretty big uphill that had a turn at the top (soft dirt) I let off to make the turn, downshifted and tried to slip the clutch some and I just killed it. so I was stuck sideways on a hill for a moment. I will call CT Monday since they received my other motor and figure out their time frame. If it’s too long I’ll swap cylinders with my stock one for now. With the FMF pipe on, it hit hard and revs to 9500rpm but while in 5th gear cruising along, 13/39 gears, bead lock wheels I’d have to be at like 6800 rpm to accelerate into 6th. This other pipe I have will rev to 8300 rpm and takes the hard hit away helped torque some.I have a hotrods LR crank & an unported 88-89 cylinder on my wife's 86 along with an 86 head, 85-86 atc head gasket(205 psi), boyesen rad valve, keihin 38as & an FMF Don Emler gold series(H-13). It run's amazing for what it is & has plenty of torque so I don't think your engine has too much carburetor. I have a feeling it’s the unknown porting you have in your cylinder.... I have a cylinder I tried porting myself years ago that I basically ruined because I didn't know what I was doing at the time. I hogged out the boost ports & did a bunch of grinding on the exhaust side & turned that cylinder into a torqueless high rpm light switch... Another thing you can try to gain torque but maintain most of the top end is switch to a flat slide Keihin 38PJ or a Mikuni 38TMX.
Doesn’t help I’ve never rode a good running 250r this one’s fun with fmf pipe but not practical.If it's drag ported you're probably gonna have a bad time in general riding.
BDT phone goes straight to voicemail also tried Facebook messenger which they’ve responded to me before but nothing yet. I will try harder tomorrow to get into contact.Glad to hear that Motowoz is taking care of you. As for BDT, are you at least in communication with them assuming they still have all of your parts?
It’s a good thing that you figured out the front brake caliper issue. I imagine that could have done some damage to the caliper or disc, or worse locked up the front wheel while riding, if you didn’t.
I’m interested to see what you find when measuring the toe differences and how it changes over the travel. I’ve never measured, but my red 250R with LSR arms and 86 spindles is pretty bad just by looking at it. Depending on what you find, do you think you will try different geometry components (spindles, etc.) to improve bump steer?
