GT125

I am guessing I will get 16 HP out of myne as the Manuals all on the net Standered say that the bike pulls 16 mynes just been rebuilt with after market parts on it for high performance

Nah not a coincidence, my rs doesn't make 45hp, be lucky to make 40 probably closer to 36 or 37 at the moment, considering its done about 2000kms on the current crank and over 800kms on current piston and ring (rebuild after this weekend).

The reason I have 45hp next to my bucket is just a joke, I didn't think anyone would be gullable enough to believe it, just as likley as say for instance a VT250 having 40hp. Ivan, you have alot to learn.

So many people talk shit that you dont know what to believe I mean someone could pull 45 horses out of one if they tried, I get 40 out of myne

On John Connor's home made dyno mine made 22.5hp. That was quite a few years ago and it still has the same everything so I expect it's making a bit less now. Comparisons between John's dyno and a local shop dynojet gave very similar readings, and performance wise my bucket was similar to buckets making supposedly similar horsepower. With current technology I can't see 40hp for a bucket though high 30s at the crank is achieveable, for a 2-stroke. Not for those pussy other pieces of shit with all the moving bits.

Homemade Dyno, HMMMMMMMMMmmmmm a new project I'm keen on it, What do you think performance wise adding a set of chambers will do I'm going to get them made to suit the bike, so that means It will have tons of small short power I want a narrow power band as well

Watching my little brother race it is going to be cool he is a pretty determined little prick

Further to the bull dismissing. What manufacturers claim is about 20% more than you would read on a dyno. They measure from the crank & are still a bit optomistic.

Their weight figures are total lies as well, but that's another story.

So what do you think is the bike is pulling in horses then, I just had it power standing up the drive more grunt than my RGV150 only problem is the chassis handles like a piece o shit, and the Aprilia motors are no good unless you tune em but the frame handles well so I think I am on the iwinning side with this combination

Who knows? A bike with a weak midrange can feel stronger than one with a nice fat one as the power hits harder when it does come.

Whilst a peak figure that you can claim sounds like a nice way to measure whose bike will be faster, it is rarely the case. Without an infinitely variable gearbox -Spread is more important

Look up the examples in Bell’s book, YZ vs RM125. Modified bikes made more peaky but end up with a spread the gearbox can’t fill.

Read read read.

OH Reading is so boring I cant read for long, Anyway in the end it doesnt come down to the bikes power it comes down to the rider, Thats were I am allright as is so it adds a perfect bit for me, my RG is slow out the corners and gets blitzed but around the corners im back on people I like leaning it over till my knee hits and opening the throttle alot sooner than normal but advice from Jay has said Im not losing on the straights im actually losing it on the exit as I really hug the inside line and dont droft out alot which brings me out the corner slowert than him

Yeah but if you did read your writing skill may improve dramatically.

I mean what does that mean?

Reading is only boring if you are reading something boring. I find a desire to learn about something I am interested in gets me reading. Use this as a motivator to read more or it will stunt your ability to learn later. The job you want when you are 40 is not the one you get when you are 20.

Then Twist of the Wrist by Keith Code etc for riding. You will learn a lot more than idle chatter from some clowns on the internet (us).

It means with the bike being fast in a straight line and having out of corner accelleration it will be good for me as I am fast around the first half of the corner then lose it on the exit for starters I hate carparks and 2 I am now so used to Manfield that buckets is hard because you are on something tighter than you are used to and it is not as flowing its all up and down the throttle and gears,

**speedpro** · 12th October 2005, 20:56

For some reason this all reminded me of Star Wars and the "force", and whether it was going to be with anyone we know.

Dave's right about the powerband thing and perception of how fast the bike is. Once I got my old TS100 going properly it felt quite sedate, but that was due to the huge midrange it had. It lost the big transition from mid to top end.

Nah I know and I believe what Dave says he is the bucket legend and also Dave I started reading last night and am learning a few helpful tips what I like to do is read the book when I need to EG if I'm working on the exhaust in the shed I sit there and read about the exhaust system just learning some new stuff Yeah I really like this place most times it has a nice atmosphere and you can learn new stuff
