Dt 125r dyno

Had this recently with someone telling me my TDR would be dog slow with its DTR cylinder and that his 4FU with 32mm would be a rocket ship. Person seemed unable to comprehend that I didnt really care that much and that its essentially a softly tuned fun / commuter bike that is designed to be reliable and run on basic maintenance only.
P codes, SP cylinders etc are all good if you have them, can afford them and are that bothered about getting 1 or 2 bhp out of a softly tuned Yamaha engine.
I've just sold 150bhp Ducati Multistrada so I'm not overly interested in 15 or 20 hp as long as the bike moves and is fun to ride
-
If I wanted to go silly fast I'd take my ZXR out for a spin
-
Yeah i know that its not a rocket ship. But i hope for little more throttle response and 1-3hp more
-
No disrespect meant from the start! But I’m guessing that you’re about 17 and haven’t ridden a great deal of bikes?
Every 125 Has been restricted to about 12bhp since the late 80’s AFAIK. Any bike that is significantly above that has been de-restricted and/or tuned.
You can unrestricted early dtr’s by ‘pinning’ the power valve open. This will give you higher bhp but will basically make the throttle an on/off button with terrible response.
Later bikes I don’t know as much. You can unrestrict them and the variable power valve will still give you better low rev torque/response (I’m guessing that is what you mean by throttle response?)Do some reading up on deristricting your year model bike, then do some riding. Stop worrying about numbers bud, enjoy a wicked little bike for what it is, before yearning for more...

Thats a big increase for a 125

Building a 900 Monster this winter for fun at a lower pace

@SpookDog I believe you could also show your License to Yamaha at time of purchase and they'd fit the YPVS for you. Hence why some came with the valves.
The latter models were restricted in other ways and probably came with the valves fitted for emmissions.

I did wonder where all the 3 wire servo’s came from. I heard that a 1000 exup had the same servo. Thought that was a 4stroke though.
I love learning new shit!Did you mean the 5 wire were emission related? Dunno, I still think they are for improving bottom rev torque. Interesting though...

Off topic. I saw the most beautiful bike ever. It was a Ducati with a ‘space frame’ of steel with about a 750-1000 v twin engine. 80’s looking. I never got a look at the numbers, never had any decals. Cafe racer, clip on looking dream boat!
I’d really love to find out what it was... -
But doesnt better spark and better ypvs map help eith power a little?

How tzr 125 makes 25hp?

Different dyno's read differently and also manufacturers often claim at the crank not back wheel

täytyy käydä toisessa penkissä ja huomaa että ei ollu pakoaukon säädin oikein kun ei penkissä menny edes 10000rpm.

just Finnish... very easy to understand
