Building a old school 350x TT racer.

I'm not to late am I?

I love where this is going, just read through the last few pages.

I've never owned a 350x, but let me through some ideas out there. <-- makes me sound credible right? :-D

As for weight reduction, has anyone attempted an aluminum frame? I know Yamaha switched some dirt bikes over in recent years. With the correct engineering, i don't see it being to much of a problem. There would be some inherent flexing I'm sure.

Aftermarket swing arms for other machines have been tubular, they look like they would weigh less.

Everything else i'm thinking off wouldn't contribute much weight individually, but may add up. The list is to large to start and I'm sure it doesn't need to be stated.

Usually the least expensive method to lose weight is if the anchor on top of the seat drops a few pounds! Not saying that's the case this time but I've seen some people drop some serious money on weight savings for their machine when they could have went on a diet and dropped 50 pounds themselves!

Love the tank Mickey! I like the look of the R scoops better and you get still get OEM ones brand new!

The frame is one of the lightest out there already, a aluminum frame may save 2-3 pounds. It does have a Cal-Fab aluminum swing are going on it, but it's really the engine that weighs so much and the most I can lighten it is 2 pounds in gears and fly wheel. It is what it is. The tank is a lot lighter then the aluminum one I seen at Trike Fest. This one will keep it at least 7 pounds lighter because you can't fill it up with another gal. of gas. lol

The good news is I don't have to drop the 100lbs. I would need to get to race weight because Bryan Ditch only weighs 170 or so.

I know I know, I said I was putting the front end on the 350x TT racer Sat. , but after 8hrs of buffing the triple clamps and forks and I was getting ready to bolt it together I lost my balls! Any one know the first thing you need to put the triples on is your balls. Took me two day of searching for them until I went and found some balls at ACE Hardwear. "ACE is the place", so I got it together today! If it keeps going like this it's going to be a long build!!!!!!!!!!!

Looking good, are you running dual coolers? Where is the coil going to mount? Why not run the tapered bearings?

Yes, we need cooler oil to the head, the highest wear area. I'll make a new mount for the coil. No time to order stuff, the race is in 9 days.

No frame gussets?

No frame gussets?

It's for flat track racing only.

Update?

[Mickey Dunlap]

Update?

Yea the update is it's fighting me all the way, 2 days to build a rear lowering kit, front brake caliper another full day. The 300ex axle is going to be a all day job machining it to line up and the motor still isn't in it and running. I have 48 hours to get it done. This is what happen when you start with the nastiest 350x Bryan Ditch had and try to build the best trike you can.

Mickey, I am running the same axle and setup on the rear as you are. instead of machining all those extra stuff, I went ahead and just made 4 round collars that are .5" thick and drilled a hole in the center. now all I have to do is find 1/2" longer bolts to bolt the sprocket on and I am done. it will hold w/o any issues. this has been proven on many 350Xs running dunes and drags and such.
just an idea to help speed it up.

Thanks but I can't chance that on a race bike.

Im dieing to see it!

I worked so many hours on it only to come up short with a problem I haven't figured out yet so I didn't get it done.

That sucks....
