    No prob, you're welcome and lots of people here know more about these than I do but as far as the engine goes, they are all pretty much the same

    Do you mean a "lightened" flywheel?

    I think ride red 250r is familiar with one of the ignition conversions like maybe a 2001 cr250 cdi box but he or someone else can tell you more about that.

    Ok, I have done a lot of flywheel weight testing on both motocross bikes and 3 wheelers and can tell you that unless you are a pro level racer, a flywheel that is much lighter than stock will not help you and will likely make you go slower . Even if you are a pro level racer, it still may not help . Flywheels are on there for a reason . If you are less than a pro level racer I would also suggest that you do not get a pro level port job either . In my experience, the best thing is to get an "intermediate" level port job and stick with that until you start winning the intermediate class . Once you are good enough to do that you can modify the cylinder some more if you want but it is kinda hard to "unport" a cylinder . A pro level rider on an average bike will spank the bejesus out of an average rider on a pro level bike every single time.

    One constant that will benefit most, if not all skill level riders is more compression.

    To be honest, a CR ignition is great but you need to "learn" how to ride the bike all over again. I used it in 2013 racing in Sikeston. The lighter flywheel stalls in the corners. The different curves on the ignition are a plus but to me the stock ignition with the OEM flywheel better suited my riding ability. Plus the sticker price for the entire kit is a pretty big deterrent. if you do get one, make sure its the 2001 and my advice is to ditch the 2001 flywheel and talk to BDT (carlos) about his "modded" stock flywheel for the 2001 CR ignition. Its beefier and doesn't stall as bad.

    Thanks for the info yaegerb. I agree on the high price of the cr ignition. The pvl setup I saw for sale would have the same result as the cr to small of flywheel. Im going with stock and I will try the lightend stock flywheel if it doesn't work I can change it. I also race drags probably more suited for that.

    I started painting some of the hubs and brackets for the 250r racer. Im just going to paint things no powder coating. Id like to paint the fork sliders and triples gloss black also the swingarm. So far the rear axle hubs, disc brake hub and lower gas tank mount brackets are painted gloss black. Click image for larger version.

    Im waiting for the weather to warm up so I can take my frame outside and do some welding on it. Also I want to pull the motor off my 85 250r and take it apart so I can send the cases to BDT for welding. I need to cut down an oem rear bearing carrier tube for my dual row carrier. I want to press out my steering stem so I can change the bearing and put the stem in a nicer lower triple clamp.Im hoping to have this trike done by April first so I can ride it and get it broke in before racing.

    Dang, that sucks. Are you putting the whole project on hold?
    Looking for a Bassani silencer for a 2nd gen tecate, the style with the movable mount. 1st gen will work
