Hi! Pls any info on vx1100 engine/ecu tune? One friend is using yamaha R1 cams on his vx1100? Also would like to rev more with a lower pitch impeller.
Thks for help

Have those parts for honda skis, plus some throttle bodies, and some r12x body parts.Will add more pictures later. Located in EU. Low prices.

i have 2 -3 of those - can send you pictures if interested.i'm from EU

Anyone tried something similar in honda's? Have 2 R12 hulls with no engine

Pls help me from your experience - 2020 exr with riva plate, intake grate, sponsoons. What else to do for best start? top spd is not so important.(riva 12/17 is more for top spd so not a good option)

pls tell me if your ski is faster with this 12/17 now? My guess is that you are slower at start and also at top spd you make less RPM then before?

think we need lower pitch like 12/16 or even 12/15. Would like to know stock pitch of ex and exr to compare it

and with stock exr impeller was doing more top speed with less top rpm(8150)

we have an exr here with tune and with 12/17 impeller is doing less rpm then stock (exr is doing stock 8600 rpm)

you adjust afr only from fuel regulator?

Hi!
Have a gp2019 - with "upgraded" 2020 pump - riva stg 3 - installed a twin imp 12/18 and is cavitating 2 times at start. Top rpm with twin is around 9000 rpm.
Is the new wear ring on the new...

Just bought a new style pump for our 2019 stg3 gp - just to have a second pump for the twin impeller - 12/18 one. First thing i don't like is the impeller/wear ring tolerance - looks a bit large....

Still waiting your offers

Pm sent to both offers - waiting your reply

Need to buy oem or AM complete pump for yamaha fx svho 2014-2017

Will start again this project soon - have a 2007 vx hull and will build the fx engine to go in

i think is another thread here arround with fx ho engine in gpr, also i would have mooved the engine as back as possible - in gp hull is easy to move the metal threaded plates under the mounts

Why the new pump is better then old one - both have 155 mm - also the new one is heavy i think

any update on here - has been done with fx ho engine and was great ski

This is an ideea from another forum - kaw 1100 pipe on yam 1200

Was looking on FB to your project - nice work

now it's my turn to do that conversion! need all info i can get on it. Also the rx di i have - is on stock pistons but they are damaged - seized pistons - no other damage - a new oversize piston set...

to 65 u eng - light flywheel, ported cases, 1.5 needle seats on carbs, shaved a bit the cyl head,air filters - and maybe will use protec pipe for 650/700 to the 1200 exhaust manifold - same bolt...

Hi! Any updates on this project?
