    looking to add a tri z to my collection

    im going to go take a look at an 86 tri z 250 from a guy who claims his parents bought it new from the dealer, looks complete and after sitting around since the 90's he cleaned it up and it started right up. i have not seen or heard it run but i want to check it out in person and might take it if the price is right. i searched around the forum and read that they have a few problems with the kicker hitting the peg and tearing up the side cover. anything else i should look for? if i get the trike im going to try to keep it looking as original as possible but make the motor more duneable, so aggressive porting, big carb, reeds, and pipe will follow. i like my 200x but just doesnt have the power to climb up some big dunes. for those of you that have built tri z, how do they run vs a similar built honda or kawi? i know the other 2 are faster in stock trim but running similar sized carbs and pipes do the tri z respond well to aggressive style porting?
    here is a pic of me on my dads tri z that he got from his friend who bought it new, that was back in 88

    Other major differences between the 85 and 86 Z is the front suspension and airbox. They beefed up the front forks, going from 35 to 39mm, and increased the travel by an inch. The 86 airbox is more free flowing. They also stiffened up the front and rear springs. I was just riding my 86 Z yesterday. With the right set of mods you can make it competitive with the other 250s. I bought mine last year and here is what I've done:

    K&N Air Filter
    DG Pipe
    Sprock Racing cool head
    Sprock oversize intake with V-force reeds
    38 mm Keihin carb
    Sprock hi-flow impeller
    Sprock billet clutch basket
    Extended footpegs (see 3-wheeler store)
    Tusk extended axle

    Here are some photos. In the near future I plan on stripping it down, powder coating the motor, and painting the frame OEM "fire red."

    I have the extreme pipe. The only difference between the national and extreme versions is the chrome. It is not like one is for midrange and the other topend. If you get one, expect a fitment issue unless you are lucky. I bought the pipe and silencer at the same time and together they were too long. The silencer hung too far off the back and didn't line up with the mounts. I had to use a pipe cutter and shorten the pipe and the silencer to get them to line up. Overall not too much of a problem but it should fit without modifications.

    DG just changed their website from the old one so there is not a lot of information yet, although the old one wasn't that informative either.
