whats the difference between the 5.5 rod and the older one? does amain have the gen 5.5? or is it gen 5?

does racefactor still do the contigency program?

and last but not least WHO HAS THE NEW WHITE GO ENGINE T-SHIRT?

thanks in advance

Hi ya Adrian. How did the fishing etc go ? Boys had a great time at the Auck Champs. Catch up soon, at the Tron most likely ?

Russell said the GO plugs and tools should be on 1 of his next orders, I got some of each on order. LOL

Actually its the other way around Thats a rich LSN masking a large idle gap.

OK ALL here is how to set your Idle Gap

run the engine for about 2 tanks , make sure its hot DO NOT TUNE AN ENGINE UNLESS ITS HOT !
Pinch fuel line
Listen to how high and how long it revs if it revs high and long you have a rich LSN masking a large idle gap

what you want to hear is the Idle rev up only slightly and die after about 3 seconds.

Use the Pinch method to check your idle gap. Adjust the idle gap then the LSN then the HSN then revisit the LSN


The HSN tune if you have to lean it will affect the LSN , so once you tune the HSN go back to the LSN and revise how it is from when yo tuned it .. if its still the same leave it if its changed then adjust it.

All carbs should be tuned this way regardless of long taper LSN or short taper .

LSN taper will govern revs up to the point it leaves the reciever jet. So it is important to get that right first.

Note a hotter engine will give a shorter pinch rev IE when its hot it will rev up quicker than when its cold . Crank case temps will effect this , thats why you only tune an engine when its hot.

Hope this helps

MM :batman:

the rod is the same in all gen engines part #28-0600

the crank is different from gen 5 to 5.5 and maybe a few other things as well but Massive will know more

hey thanks all who gave me tips

3port R tuning issues
 

Have 2 GO 3p Race. Both have approx. 3/4 gallon on them. Both having same issue. Lean bog on low. Trying to race tune and when i punch the throttle, boooooooggggggg....richen up the low end and it goes away. With this much run time, shouldn't i be able to lean everything up a bit. Both idle great, but getting the temps up is very difficult. Do i have to wait for the metal pinch to go away a little more? I have a go 5p and never have had any issues. These 2 mills seem to want to tune backwards of every other engine i have. Suggestions/comments.....thanks

lesson learned
 

i learned a good lesson last year .....motor kept leaning at half tank of fuel so i tuned it with half tank.. then filled tank up and it was to rich ...chased a tune for awhile..because i checked carb, fuel lines,filter, plug

long story short fuel tank pick up had a crack in it and wasnt sucking in air untill i opened throttle up on runs so i didnt see air bubbles in fuel line while car was stationary switched tanks and motor was perfect after i went back to old needle settings...

dont allways assume its just your motor ....clear or semi clear fuel lines is all i run now makes it easier to spot air bubbles

not saying this is the fix to probs some of you are having....just remember it could be

all these team guys and no one can tell me were to get the new white t-shirt?:lol:

Have you tried to keep LSN as it is and richen HSN ? Also I assume the idlegap is as supposed. 3/4G should be enough for the 3p to settle in. However if you still have mechanical pinch so don't try to lean it too much just run a bit rich.

will novarossi cooling heads fit a go tech? I ask because I am rebuilding a 5pt I had with 7 pt parts but I can't find my original head I know I still have it somewhere...or will a bmods head fit?

lmk

thanks,
Jayson

I have seen both them heads on GO's before.

HALF TANK BOG

This is what happens when the HSN is too lean .

At half tank the over all tank pressure is less so when you go to give it gas it bogs . How lean the HSN is depends on how soon it happens in the tank IE if it happens at half tank richen HSN 2/8 if it happens and 3/4 full richen 3/8 if it happens at 1/4 full richen 1/8

its common when you get lean bog people go for the LSN and find it dosent really work. This is because the HSN governs the inlet of fuel over all over all , when you have low pressure in the tank the engine starves for fuel , the HSN needs to be richened to allow for a lesser pressure to feed the engine.

I have 2 MM 5-ports coming, 1 for my buggy and 1 for my truggy. I would like a little opinion of folks w/these motors, usually I would run the 086 pipe based on what folks on here suggest, but our new track layout is much tighter than before and I wanted to know if maybe I should drop to the 053 or the 007 pipes??? The track is tight, jumps w/little run up, and not really any straights to let the motor stretch out. I know the 5-ports are very strong on the bottom, but I see most folks putting on torque pipes for their Novas, and GRP's (that's what is popular here, not many go's) and wondered if I should be running a torque pipe also or stick w/the 086.

What do ya think??

If their modded motors from MMods you will have more bottom end than you know what to do with :nod:
The 086 suits the 5 Port very well, giving great bottom end and reasonable top as well. If you were looking for another pipe I would get the GO FEMCA 0801, which also complements the 5 Port well.
I run a modded 5 Port with 0801 in my buggy. We have some tight sections on our track with jumps just out of corners etc and the 5 Port with this pipe handles it with ease, and thats running a 6.5 restrictor and softer clutch to calm it down a little.
You might like to run the 086 in the buggy and the 0801 in the truggy. The pipes are similar, but I think they would be better suited in this configuration going on previous experiance.
Enjoy those motors - you will be very pleased with Mark's work.

I think you'll be fine with the 5PT + 086 combo. I have tried the 086 and the 0801 on my stock 5PT and I feel the 086 is smoother on the bottom than the 0801 (still strong though). I feel that the Go 0801 pipe pulls harder with better run times as well.
