The figures were stupidly low, anyone can chuck a FCR and exhaust a DRZ and get 40bhp but apparently mine is only 33bhp (well 36 in the video when it was running lean). Having ridden a DRZ bone stock for 2 years I know for a fact it's a lot more than 33bhp. The stroker should definitely be putting out low 50's, it's an absolute animal.

Awesome, shouldn't be less than 35bhp I'd imagine. I need to get mine on one and see what it's got. (Also has E cams and FCR).

38 minimum with those mods with dodgy jetting.

I need to get myself to another dyno, willing to bet the bike that his dyno is under reading by at least 7bhp. A stroker 462 is low 50's easily. 44 is leaned out 400 territory.

A bit pissed off about it really, I know the bike is fine, so do the other lads who went but the numbers are just contradicting everything. The lad with the 462 went to the same place last year when it was just a big bore (no +4 stroker or FCR41MX) and it got 46 so yeah, that says a lot, 2 less bhp with a stroker crank, sense, it makes none.

Where was that dyno??

I believe Turbopacs do free dyno's on a Sat morning, might be good to get the bikes on a different machine Thumbs Up

It was through Paul Gowland in Hexham.

A few people have mentioned Turbopacs now actually, where and what is it? Surprised

Edit: ok so they are in Durham, seems like they aren't doing free runs at the minute. Seems odd anyway, they have nothing to gain from it anyway. £30 for a power run, £45 for data logging from what I can see.
