FYI people Max Power and Ninja engines also have Long LSN's :D

Its becoming popular because its a much better system for carburation. Mind you these engines have had them for a while ..

The problem is not that there is a long LSN , Its the Manner that people tune carbs ... The biggest problem being perpetuated on the net is incorrect tuning procedure. You can see it all over You Tube and Forums alike .. People tuning the HSN first is the road to a bad tune. No matter what carb you have on no matter what engine you have you MUST tune the LSN and idle gap relationship FIRST ! then tune the HSN then re visit for finer tuning when the engine is at temp.

the Long LSN is a much smoother and more economical form of metering the fuel spray. Thats why its being used. As people want better economy out of their engines the need to regulate the fuel intake becomes greater. LSN's are the only way to do this without bolting an ECU onto your engine.

MASSIVE ! :batman:

No problem. Just glad we are able to help out now and then. This sport has a steep learning curve, so every little bit helps :nod:

Exactly, I won't run a short needle lightswitch. No consistency with that setup, No point in the short needle!

MG66 is a GREAT motor btw!

What do you guys think??
 

I don't mean to barge in here guys. This thread is LOOONG...it must be a testament to how good these GO motors are (at least I hope). I'm new to racing scene and have just bought a Jammin X2 CRT and have been reading about the GO motors but I've got a few questions. My questions are:
1-should I get one and which one should I get?
2-where is the cheapest place to order it from?
3-What pipe should I run?
4-What fuel is best for longevity and performance?
Since I'm new to racing I'm not quite over the sticker shock yet so I want something that's going to last a while and be fairly cheap to begin with. Also, my local track is fairly short so I was thinking about the 5 port, but I don't know.
Thanks in advance guys.:)

No online sources??
 

I'm in Aldergrove, BC, Canada. Which is faily close to Washington state but I don't even see one for WA. Are there any online sources for this motor?

For truggy get the 5 Port Combo Kit with GO EFRA 2072 pipe - this set up will have all the bottom end you need, plus great top as well :nod: Perfect for truggy.

Massive,
can you please make a short tuning video for hopeless people like myself :-)?
It does not have to be a state of The art film.
Evev a mobile video would help me a lot.

Thanks

Frode

Good idea.

Mark Grizz or myself will work on doing one, the main thing is to use a cam with a good mike so can hear how to do bottom end properly from scratch and what to listen for etc.

Thanks :-)

I'm sure Grizz will chime in, he has explained it verbally quite well on here some where.

Have you read back a bit ? or the tuning bibble post grizz posted ? or the MM site ?

I'v got a big race in 2 days time so I won't have time, so could take me a while to put something together, and I assume your wanting something ASAP ?

I have read all posts since page 1. But The way I work, I have to see/hear to fully get it :-/

Do it when you can.

Frode

I'm dyslexic so I have trouble with reading instructions as well but the site Grizz links on page 776 first post really helped me. Even I understood it.

A picture paints a thousand words as they say :nod:

I am not set up for video at all, and I know Mark is probably way too busy right now to do something. Flanno ?? no pressure bud :D

Seriously though, I am sure someone will put something on video soon and post it on You Tube etc. I really think it should come from Massive himself when he has the time. Most of the methods are based on, or come directly from his tuning guide, so it would be appropriate that it was a Massive Mods production.

For those who struggle to transfer what they read into practice, it can be a bit tricky. Just experiment.
Just as "a picture paints a thousand words", it's also true that "practice makes perfect". Most people who are really good tuners, and have an ear for engines have probably spent countless hours trying to perfect the dark art of tuning, so it's not something you can learn overnight.
It's not going to fall into place straight away for everyone, but playing around and finding things out is half the fun - yes ?

I have just re-written the tuning guide on my site to make it a little easier to follow, in simple steps with explanations and referals to Massive's tuning tips along the way.
Go to the bottom of the menu on the home page of www.go-racing.co.nz and click on the Tech Tips link.

+1 all the above. :nod:
