How does your restricted 33bhp pointy SV650 feel?

But if restricting needed a replacement ECU, surely the process would cost more. Since ppl here say that an ECU costs between £200 and £400 (depending on the threads you read).

If you can do it without changing major components, surely that's better and cheaper...

Since the restriction modification (parts and labour and certificated) was less than £150, that suggests it wasn't a whole new ECU.

Does anyone know for certain? "I reckon", or "I imagine"... not so handy Someone here must have installed/removed the kit themselves...?

I had my K6 restricted to 33hp, It is done by replacing the ECU. I put the full power one back in and it is a dream. Once you ride it on full power you wudnt want to go back to the 33hp. Sounds that the garage did a botch job. Mine was done at the main dealer when I bought it new. I would get a second opinion...

The ristriction is purely electronic and no washers and such.

The bike is as smooth as ever but it does lack power...as I revved it towards the red line. it did not do much and lost power kinda...although it could be simply the rev to horsepower graph...it may be giving its power at lower revs and so no point revving it at the red line.

The restricted ECU costs about 100 quid from a main dealer, if I remember correctly..

I removed the kit myself, its a plug in ECU, took about 15 mins in total

Got her to find the paperwork and certificate. It says the items installed are an "inlet blade" and a "throttle stop". Definitely no ECU gubbins...

The bit I am really interested in is the bike performance. It seems fine 95% of the time, with the odd hiccup. Thanks for the feedback folks.

Be interesting to hear from anyone else who has their pointy restricted the mechanical way.

I had a SV650S K3 that was originally restricted by having a restricted ECU box that was then swopped with the normal ecu when de-restriction came about. imo it is far more normal to do it this way (for pointies) than to do it the way you are describing.

As far as how the bike felt, it was fine, the only real difference was that you couldn't really accelerate past 100.

Using info from the certificate I've found the supplier of the restrictor:

http://www.fiinternational.com/Restrictors.asp

Its the 04-WVBY-K25

Unfortunately there's no extra info on their pages at all. Still, confirms what the shop said.

Yes, normally pointy SV's are restricted via a replacement ECU. However, I can't see why a mechanical restriction wouldn't work too, or why it might cause a problem.

I've got a restricted ECU kicking about if you want to try using that instead.

Thanks for the speedy responses, people It sounds like its worth me checking the performance more closely and figure out whether I was just trying to make 33hp behave like my usual 100+

I don't want to kick up a fuss over nothing. Nothing worse than being told "Nah mate, they're all like that" and having no idea whether you're being spun a yarn.

Cheers!

PS. Flamin Squirrel - We might take you up on your offer if the bike is behaving weirdly. Thanks for the reply!
