Which is best carb or fuel injected

[quickordead]

Hi all! I'm very new to this so please be gentle with me.
I'm planning to buy and build a tR1ke very soon, just sorting out a day to visit Paul for a test drive and then look out bank account. My problem is which donor bike to get. I can get a very reasonable front end damaged 1999 bike but was worried that I should really opt to spend more and get an 03 04 fuel injected one for better performance. I know carbs are easier to work on but is the performance going to suffer. Any advice will be greatly appreciated.

Many thanks in advance.

The demo vehicle is on Carbs, Get Paul to take you for a blast, you will be blown away by the power of that machine, I opted for the 2000 Carb model, it came down to money for me, and the TR1KE is designed around the earlier models of R1, however RTR will redesign anything for you at a cost, However there are some builders on here have opted for the newer Fuel Injected models, take a look at the other ongoing builds on here.

Trust me though, 150BHP is more than enough fun for anything weighing in at 350KG

Can't wait for my kit to be ready, just wanna build it and get it through its test for the end of this year.

Cheers

I bought a 2002 which is fuel injected.
Carbs are easier to work on when there's only one or two. When there's four I think that it becomes much more difficult. That's just an opinion. Fuel injection while more difficult to work on rarely needs work. I think of it as a reliability issue.
The 2002 thru 2004 have the same bolt locations as the earlier carbed models.

Just my take on the issue the performance of either will be just fine.

Thanks guys, the issue I think will come down to cost and reliability. It will be quite a bit cheaper to get an earlier bike, but the injected engine seems better. I've got someone who said they can remap the injected engine to race performance but at a cost. This could be a longer project than first envisioned, but I'm in no rush so if it takes 3 to 4 months saving for the better engine and tuning costs then.....
That last bit was typed in a whisper so my fiancee couldn't hear.

I have made the same considerations. Pro and cons:
A Carb engine:
+ cheaper
+ has a "more than strictly necessary" powerrrrrrrr
+ fool-proof engine (Each motorcycle engineer can help you to adjust and synchronize the engine. An engineer at the Yamaha dealer told me that the carb and early injection engines are really pool-proof. Later injection are more tuned and a bit more sensitive.)
- choke cable installation

An injection engine:
- more expensive
+++ has "far more than strictly necessary" or "perhaps more than the driver can handle" powerrrrrrrr (25HP extra)
+ no choke cable installation

I have chosen a carb engine. 150 bhp with 400 kg (car + me) is more than Ok.
€ 1000 extra for just 25hp...
I invested more on handling than more power. So new and excellent brakes and low weight wheels.

I went for the carb option! would not consider the power side, both will be far more powerfull than you will need. I think you need to judge the donor bike, miles how it runs/ been serivced etc then make the desicon, oil changes are a good sign of maintance. Not sure about the later models but on the carbs engines second gear can be a problem .

best of luck with your choice another tr1ke build will be good to see.

Hi Lee!

Welcome to this forum!
I am just one step ahead of you. Last friday I purshased my Donor motor. In my thread you can read why I opted for a 100% bike instead of a damaged bike or parts only:
www.mevowners.proboards.com/index.cgi?action=display&board=tr1ke&thread=2141&page=1#15231

The reason for chosing a carb donorbike was based on several pros:
-low positioned axhaust looks better. I may change the exhaust angle in a horizontal position just for the view on the wheels.
-For what I have been told the early versions have been designed to be bullet proof and the injected versions are redesigned to be more powerfull and lighter. Because of this the injected version may have a shorter lifespan and may be in need for more maintenance.
-I wanted an silver swingarm, most later versions tend to be black.
-smaller loom, less rewiring.

con:
-aluminium parts may have a math finish due to aging.
-only a few have the original exhaust (titanium blue on mine)

It took me a while to make up my mind on my bike. The low milage was a key factor. As per accident it is a late carb version but from what I have been told all carb engines are identical. Chosing a late carb version may be helpfull to sell the fairings.

good luck!

I chose the newer 2004 model (180 bhp with exhausts fitted above the rearwheel). Be advised: the frame needs some modification and you will have to fit an aftermarket spring on the rear. Also, the wiring is a lot of work...

The tR1ke is now manufactured for all R1's up to 2006 so no frame mods will be required if you decide to go for 2004 to 2006 injection donor.
The exhaust however is less straightforward on the later bikes as it come out under the seat instead of at the side of the swingarm.
147 bhp is plenty of power though.
Handbrake kit now available as well as reverse.

147BHP is like a rocket mate, my tr1ke is very vicious, you will not be dissapointed with this. Just try and find a lower mileage version, and preferably drive it home so you know its working well.

I have a few issues with mine at low revs, but the demo doesn't have, so I can only assume my Carbs need cleaning, a standard 2000 year 147BHP R1 is a mental motorcycle, and its just as crazy in the TR1KE, the looks we got on Wednesday were great, the noise from the standard can was very impressive too, can't imagine how bonkers its going to sound with my race can on.

I have driven m R1 only 500m and when placing her on a trailer it decided it was a good move to bring her to the local motorcyclemechanic, give her a service check and let her rip off the rubber of the rear tyre on the dyno. 145 rearwheel hp it is and the gears have been extensively tested and carbs finetuned. Yes, this will cost you some cash, but you are in need to give the engine a service check anyway before you start takeing her apart or when she has been converted to a Tr1ke. The only downside is there may not be many many experienced motorbike mechanics with a car testbed to test the engine in a Tr1ke...

My testbed will be the road :-) And unfortunate boys in toy cars :-) By toys I mean, Porsche and Lotus.... :-)

LOL!!

A decade ago I had a well known Ducati mechanic finetuned -10HP. He did this by audio and testdrives which took a lot of time and money. Later the bike gained 13hp on the Dyno which made it clear never to mess on the carbs without a Dynotestbed. On my Monster an other mechanic adviced me to buy 2nd hand carbs because they appeared to be worn out and there was no option to solve the hickups at low rpm. A dynojet kit+revisionkit+Dynorun made this the smoothest engine I have and I'd wished to place this in a Tr1ke as well (or eco-exo which is a good match for the power/weight ratio)

I always thought professional mechanic experience is the best money can buy but now the only things I thrust are graphs and measuring tools.

I do hope cleaning the carbs will solve your issues.

greets!
