Thankfully there have been no more dramas with my Bonnie. Took her out for a spin today and she seems to be improved by the extra tooth at the front but I'm now wondering if I might go another one tooth bigger or opt for a smaller rear sprockets. Does anyone know if the 790 Bonnie's are restricted? I've seen a claimed top speed of 115mph for the 2001-2 790's but when I was out today I was coming close to the 100mph mark, which is near enough the red line on the tacho and the engine just seemed to lose all power very briefly and the went back to normal as if, at 100mph some sort of limiter kicked in. I think my other Bonnie can get by 100mph but never seen it on this one.

Not the same bike but my Triumph Sprint 995 had a restrictor. I found out on a track day at Donnington, I'd only had the bike a week so hasn't had a chance to open it up. I'd booked the track day up when I had an R6 but didn't want to cancel it.

I've got a hard copy of the Triumph workshop manual @Don the Don but I've been too lazy so far to go and dig it out so I was hoping that someone might have done a spot of legwork before on the subject. I did see a piece, in a documentary about the history of the Triumph Bonneville, that was a review when the bike was new and the reviewer said it was had a rev limiter. The gearbox on the 790's is the only flaw in an otherwise brilliant bike for me. The revs are way too high at 60-70 mph as far as I'm concerned and you feel there should be a sixth gear to take the rpm's down a touch and the fact that it hits the redline on the add on rev counter at pretty much dead on 100mph seems stupid to me and you really can't improve that much on the sprockets because taking down the rpm's at the top of the range equates to being too tall in first gear.

OK I guess the Bonnie is supposed to be sedate, vintage, biking but, with bigger jets and TOR exhausts like wot I've got it feels as if it wants to be able to go faster.

Today's task was pulling the Daytona out of the shed and giving her a look over. Apart from touching up a chip out of her paint on the tank and cursing the, thankfully small but still very annoying, blisters on the tank she looks to be none the worse for having been neglected and so I reckon that both her and my blue Bonnie just need me to get them down for MOT in the not too distant future. I have to say that the Daytona may not be the fastest, most modern or most user friendly 'superbike' but she is a beautiful looking machine and that 955 triple sounds tasty. The only two bikes that may not get an outing this year and which actually need a fair bit of tidying up cosmetically are my Royal enfields as the chrome on the exhausts in particular is covered in rust spots and the alloy needs de-furred too. Surprisingly the wheels are in better nick than my Bonnie's. Maybe Indian chrome is better than Italian?

I've been thinking about getting stainless rims for the Bonnie's but, even building them myself it's something like £160 a wheel in spokes and rims plus requiring expertise and a jig to put them together and maybe buying used hubs to lace up I reckon it would be something insane to buy after market wheels. There is a company in England who sell them but they don't give a price which suggests it's pretty bloody scary.
