Hello everybody!

I am beginner with this nice bike and now i need some more power in it.
I will be riding trails and some desert racing type of riding, so i hope to get power to lower mid range rpm's too.

Now i need advices where to spend my money from you who know this machine better.
My english is not that good and that's why it is really hard read every topic from this very informative forum.

- Cam: wich cam you suggest to my type of riding.

-Head: porting of course, but stock valves, or +1, or even bigger??

- Intake and throttlebody: what intake you suggest and is there any aftermarket TB:s for sale or just stock ones bored +3mm oversize?

- Fuel/ignition module: Many of you seem to like EHS bullet box, but that module works only for adjusting fuel right?
What have you done for ignition? Or rev limiter?

- Exhaust: I'am looking for quite silent exhaust with good power output. Barkers seems to work fine with EHS Bullet Box, but is there some other?

- Big bore kit: Has BBK any advantage compared to high compression standard bore. What about reliability?

-Crankshaft: This is something i will do, but is there some other version available than Hot Rods +3mm?

I know that there is many guestions, but those mods i have planned to do IF you guys think they are worth of wasted money.

If you some aftermarket parts to XX for sale, let me know.

Thanks for your help.

Holy smokes man! Do you have a Lamborgini you need to beat? The only time I have ever had a power problem is when I tried to pull up 75 feet of underground power cable. I had to use my wifes 4x4 and it had problems. Just my preferance but for me a 13tooth sprocket will give you the low end enough. I have never had problems in the dunes. My recomondation, before you go crazy use it in the places your going to ride first, see how it does, who it won't beat, (not many likely) then make changes. you may find that a few tweeks here and there will give you what you need and won't keep your machine layed up in the shop. Heck all the snow you get put on some skis and a pair of Mat Tracks.

Thanks for your reply.

I agree, that there is nice amount of power even in the stock engine, but i still want some more and reliability is really important.

Here in Finland we do not have many Lamborghinies, but some other guite fast machines like this one (i will not be racing on ice...):



I will be riding trails and roads "rally raid" type navigation "races" where speeds are usually 50-65mls/h, so i think i need to go to 15 front sprocket.
That is the reason why i sold my Renegade, cause it was hard and expensive to change gearings to it.

Another thing was fuel economy, cause my Renegade used about 13 litres/65miles. I think XX takes about half of that?

I hope that when i get little more power to my XX it runs 65mls/h nice and smooth without engine reving too much.
Daily routes can be 100-350 miles in those "races" what i will be riding, so reliable power is what i am looking for.

Here is little video for you to see what kind of roads i will be riding in Finland:

That link to second video you posted, I seen nothing in that you would need more than 4th gear in a stock Trx700. If you have the funds and the means than certainly do all the work you mentioned! But you may just be impressed with the factory ride! I think the best thing you can do is change the air filter. And then the sway bar is a must have in my book! After this get the full exhaust and a fuel programmer to complete the Big 3. Then maybe go for a drop in stage 3 cam. And after this maybe more...Or if I had the money this would be a option of choice, after the big3 is complete

oh yea don't forget the tyres!

Thanks for your advices!

I do agree, that sway bar is must on XX!

In that video we were on some of the smallest roads from that day where speed is low, so i think XX will do that easily.
Video is just for show what kind of riding i'll do with XX.

I have ridden XX only few time and without GPS, so i do not know speeds, but XX pulls very nice even now when its stock.
I still hope to get better acceleration on 4-5th gear to get it sideways easier.
I know that sway bar will make it easier, but power is also nice thing to have...

As i told, i hope to get engine wich can run all day long 65ml/h and temporarily 75-80ml/h but still accelerate guite fast.
That is why i hope to get informations from you guys what mods i should do and what is absolutely waste of money or will be bad for durability.

I have crf450 with Athena 490BBK and HotRods +3 crank with ported head and and stg2 HotCams.
I really like that setup, cause there is so much power that even i have geared it really long it still accelerates good.

Thanks again for your tips!

The best option for you is doing the work one time and buying the right parts. If you want good reliable power then stay with the stock bore cylinder, big bore kits vibrate bad If the piston is not matched to the weight of the crankshaft. 11:1 CP piston or 12.5:1 if you can buy race gas in your area, a Web 290 camshaft, hard welded rockers and heavier valve springs. A +1 port and polish on the head, and a nice quality full exhaust. I would suggest motoworks if you want to keep it quiet. You will also need a programmer and with the extensive motor work I would suggest a dynojet PC5. This setup will have to be dyno tuned to get the proper air to fuel mixture and you should pull 60+ horse power. Also some heavier springs for your clutch.
