Have I done the right thing R100S

[B Murr]

Nervously fed in the clutch and off we went!
First application of the front brake brought back memories of the brief test ride omfg how can they be that bad, 4 miles in I am more relaxed pleased with how willing this bike is to swap lines through the bends, it's way more comfortable swithching line than a Zed of the same era but lacks the grunt of the Zed out of the bend, we pull up at a T junction and it's running at 3k popping back and surging, think the floats are flooding the carbs, onto the main road we pull willingly to 70 cruising speed for 8 or 9 miles slow to stop again at a mates house still running at 3k with throttle off I hit the kill switch pop pop loud bang it stops then proceeds to piss petrol out of the right carb at a fair rate switch off the petrol and already have a 20inch dia pool of petrol under the bike. Please tell me what's the fix ?
The return run home has the bike still running at 3k with the clutch in between gear changes but much more brake effect the more I use the front brace the better it pulls up and I am enjoying the ride through the lanes, as I open it up a bit more it holds back every now and then like fuel starvation, I must have carb problems.

Common issue with the carbs, can be a sticking float needle. Clip off the bowl under the carb, jiggle the float a few times with a finger and put cover bowl back on.Chances are its going to sort itself with that. Worth putting inline fuel filter on to stop crud and grit getting through to carb, tank probably should have been flushed if standing for so many years and I'd guess carbs will thank you for an overhaul, carb overhaul kit available from motobins or motorworks. Pleanty of threads about on the common issues with these bhikes, look for them through the 'search this forum' search link above.

Enjoy. The brakes are less of an issue: you will adjust to slightly less urgent riding and engine braking counts for a lot. Otherwise, as above!

The frustrating thing is with a couple of hours work those bikes will run beautifully.

There's an adjustment probably needed on the brakes (the calipers swing on an eccentric pin) if they aren't right they are terrible.

As mentioned above the carbs probably just need cleaning out and setting up. You will need vacuum gauges to get the best out of them.
