Default My finished Felt 1903

so here it is...it took three months, and I couldn't have done it without HB Local and Clotho...thanks for the tips and tricks. Thanks to Creative engineering for the sweet clutch kit, and CW racing motors for balancing the crankshaft. The head and jug were lapped, and dowel pinned on two diagonal studs to the case for a tight fit (there is way too much play in those stud holes, enough to rattle and effect the timing), and I made a copper headgasket. I ported the intake and exhaust, myself, as well as fabbed all mounts. I mounted the CDI sideways so I could use the holes for the mount screws as cable routes for the clutch and throttle, which turned out pretty clean. The electrics will be in steel braded like the fuel line....no zip ties on this build! Unfortunately, it's pouring rain for the next five days or so, so I'll have to wait a bit for hte maiden voyage....can't wait to experience that balanced motor.

That sure is a beauty. Bet you'll get lots of looks, double takes and questoins when you ride that thing.

Looks great!

The rain must be driving you crazy. I know I would be going nuts.

That is a bike to be proud of for sure!

Really nice J!!!

I can't wait to do a Felt. I've been wanting to do one up for a couple of months, but I've got new engines I'm working on so it will probably be another few months before I do a Felt project.

I really like the way the top tube can be sealed for a fuel tank. How much fuel does it hold?

P.S. Glad you liked your clutch kit.

Jim

The tank holds a bit less than a gallon...on the Felt steel tubed frames it's about half of that.
Thanks for the positive vibes everyone...my buddy and I started building our Felts at the same time, and his will be done soon...his is a vintage iron Husqy with the 3 speed hub with the jackshaft kit. I almost want to ride his more than mine! I'll post some pics of his when we finish her up...Any jackshaft kit tips Clotho? How about fitting the kit to the Creative Jim clutch kit, anyone? The housing sticks out a 1/4" past the stock one. Also, can the stock chaingaurd work with the jackshaft? I know we're gonna drill the stock chainring to the jackshaft bolt pattern so we can use it instead of the plain one that comes with the kit, but I think we'll have to notch out the top of the chaingaurd to make room for the drive chain.

Finally got a chance to go for a good ride today, and, oh mama, what a difference a balance crank makes. "balance" may be the wrong word, though, because what I did was I had the crank checked at a shop for concentricity, and they found that it was six thousandths off on one lobe and 3 on the other (normal for a two stoke is 2 thousandths). By torqueing on it with a press, they got it within 2 on both sides, but no grinding or drilling was done. This bike rides like honey now...the springer fork is plenty of cushion, and with the rubber-mounted motor, it feels like riding a nice moped or scooter. The last detail is to get one of those Pipelyne pipes fitted and she'll be ready for promnight, boys...I got her up to 38mph today, and she still hadn't taken all the throttle.

I'm glad to see a few guys are starting to isolate thier engine mounts. It really makes a difference. Both your engine and bike will last a lot longer.

That's the same Felt I touch at the bike store. They do lay away now but the wife is the queen. I mean how am I suppose to convince her I need a bike #4?
