The standard Vara can be a real weapon in the right hands anyway away from A roads and motorways, which is why I've kept mine for so long. I only bought it to use as a work bike. But after taking it all round Portugal & Spain twice, I love it and wouldn't swap it for anything.
I wouldn't mind trying the later F.I. model but the old Vara would have to stay. Besides I'd probably be trying to find ways to graft the sp1-2 injection system & throttle bodies onto the thing and the the pennies would be dissapearing.
The firestorm cams & carbs cost a lot less than the remus cans and thats where the extra power's come from.
I'm thinking of taking it to the dyno to see what sort of increase in power its got (just out of curiosity) and I'll post the results.

Did you have dyno'ed before the work It would be great to see the real difference, Thumbs up to great work

No benchmark Dyno but the bike was bog standard before I started so reckon the standard BHP quoted should do for comparison.
Going to have to get it done soon if folks are waitin to see.

Thanks for the interest.

Had the bike on the dyno this week.
I've got the printout but I can't upload the attachment for some reason.

The standard setup was taken from an earlier dyno run on a stock carbed Varadero.
Max. power up from 82hp to 98hp.
Max. torque, no change at 64 ft-lbs

The power curves are similar up to 7000rpm. The stock setup levels out after that but the new setup carries on climbing straight up to 9000rpm.

Both setups reach max. torque at around 4000rpm but the stock setup drops off considerably after 7000rpm where the new setup maintains torque all the way to 9000 rpm.

The dyno guy overlaid a firestorm dyno run on mine and the power curve was actually lower than mine. Only reason the firestorm made more power was that it revs to 12000rpm where he wouldn't take mine past the redline of 9000rpm. He reckons if he had done then we would be looking at 110Bhp on the vara easy.
You can see on the graph that the stock setup just runs out of puff after 7000rpm

The next stage of project Varastorm is to procure some firestorm valve springs to prevent valve bounce and raise the red line a bit.

When I had a Firestorm, getting it Dynojetted made a huge difference to the throttle response. It may be a good idea to invest in some more dyno time and get the carbs professionally tweaked to make sure the fuelling is spot on too.

You've just done exactly what I'd do to a Vara if I had one

This 2001 Vara have had the complete cylinder heads, carbs and exhaust pipes exhanged to VTR parts.


(Not my bike!)

Owner reports to have a maximum of 105HP.
Maximum torque of 97,5Nm.
Approx 90Nm or more betwen 2700 rpm up to the rev limiter at 9800rpm.

It also have Remus Grand-Prix silencers

Well Kjell
Looks like youv'e just set the bar with that one.
My goal is to reach 110bhp @ 9000rpm and as much torque as I can get through the range.

66 ft-lbs @ under 3000rpm eh.
Mine made 60 @ 4000rpm and stayed around there all the way to 9000rpm

That Vara sounds like its pretty sorted.
Same colour as mine too.

hi guys..just what parts of the vtr would i need for this ..as i have the motor out of the the vara,,and the good bit is my mate has a VTR.. thats dead but the motor is ok.,so any help from you guys would be great as you are on thr right track..

Nice. Looks like we have some converts.
I've had to pick stuff up here and there when I can and youv'e got a full engine to molest.

if I were in your position I'de go for the the full engine transplant. Not sure wether you can convert the clutch actuator from hydraulic to cable or wether you need to fit the hydraulic lever off the firestorm though.
Your gonna get an extra gear though which may be a good thing or a bad thing depending which side of the fence your on. I prefer the five gears and mine has easily done an indicated 140mph with 5 gears.
Failing that.
Cylinder heads (complete)
Carbs (obvious) Dont forget the airbox though and the throttle pot plug was different on mine (just rewired it through connectors). Get them dynojetted as per dynojet stage 1 instructions (firestorm kit) My fuelling was all over the place with standard jets & needle (down to 120miles to a tank full.
See if you can fit the firestorm exhaust headers cos the collector box is a better design, much smoother looking.

Thats all the bolt ons. If you don't mind stripping the engine fit the firestorm pistons for more compression.

Put it all together and happy days.

I only wish I had a mate like yours.

he crash the bike..but motor ok the rest is u,s sounds like a lot of hard work but may be over the winter...me thinks heads cams airbox pistons+pipe work..u say the fueling went mad..120..have you managed to sort it out to any ware near the right mileage..what about cam chain tensioner,s VTR or VARA..as the vtr tends to be a bit week?? have you still used the 150-70-17 rear tyer.

Fuelling is now sorted. dynojet kit with f180, r180 and needles set to 4th slot (from top)with K&N fitted. I am going to modify the airbox by chopping the lid off, so I'll probably be playing around with the settings on the carbs again.
I think the cam chain tensioners are the same units but you can get replacement manually adjustable ones. The VTR guys seem to like them.
Anyway you'll be able to tell when you inspect them yourself.
Still on standard tyre setup with conti trail attacks which are excellent, best tyres I've had on the bike yet.
