I liked doing my work closer to the ground. Kinda depends who you are lining up to pilot these. Young flexible chap wouldn't need such frivolities.

The other thing to consider if the stock tank is used is the rider bending over the rear of the tank. Younger leaner riders will be better at it than say the more mature and rounder riders. The higher seat will help with that at the expense of the head down bum up riding position. Me, myself, and I, with our unjoined wrist fracture and crunchy neck have a bit of an issue with that riding position.

I'm hoping that I might be able to run the bike on an eddy current braked dyno. Still discussing it with a youtube guy who has one. It can do programmed steps or slopes or set speed or rpm so will be perfect for tuning the ECU.

With no fuel or oil the MB100 engined FZR weighs in at 86K. Not great but not too bad. The tank weighs 5K on it's own??????

[F5 Dave]

That's actually not too bad. I think my H100 steel frame was like 81. Maybe with gas, but not a mile away.

Not a 50 mind.

Good to see you cleaned your fingernails before making the vid.

i like how the exhaust pipe muffler has the same angle as the seat.

In the nov video what is the reed rubber?

Early IT175?

[speedpro]

I'm not 100% sure but I think it's from a RD350. New holes drilled to match the MB100 mounting holes. The reed block is from an RD as well but as you can see I've added a splitter. I also removed the supports between the reeds on each side and fitted a single .4mm CF reed each side. There's a bit of devcon inside the reed block which makes it look a bit smaller but it flows well enough going by the horsepower.

rd350 makes sense slot the top two a few mm wider and redrill the bottom, with those, but i thought you said 32/34mm carb?

[speedpro]

I did run a round slide Mikuni 32mm carb on this setup previously. This time I have a 28mm round slide Mikuni. I expect it will be a bit easier to ride.

okay so you can squeeze in a 32 on the old rd rubber? or did you use another one?
i have been trying to find straight ones to go with the 34 ish Keihin carbs i have fo the LC
i was going to try some Snowmobile ones.

So I bought some billet ones after kit ones split. Then to mikuni spigot type. Had a silly name. Might come to me.

chariot?

You had the UPP ones that split?

[F5 Dave]

Chariot off Ebay, yes pretty sure. UPP ones split.

Just thinking of course the size is CR250 on CPI barrels, but they do a range I think.

Back to the FZR125. I've been messing with it a little bit, just sorting out everything so it's good to go for racing. I have the starting all sorted now and can fire it up with the 2nd pull on the back wheel every time now. After taking the cam cover off to torque the head studs and check shims I put it back together. When I first fired it up it had a little oil leak but fortunately after spraying a bit of brake clean around I was pretty sure I found the little gap leaking oil. I super cleaned it and pressed sealer into it and it seems to be all good now. At the moment I'm aiming for Tokoroa at the end of the month. The other bike with the MB100 will hopefully be all sorted as well. It seems to run OK but I would prefer to check it on the dyno rather than risk a problem at the track. 10 year old tyres with 1000s of dyno runs shouldn't be a problem, I'm hoping.
