carb modification

[stroker]

@evermove : yes that look like TMR28 with TPS, but no accel pump.. how much is it bro ?

That's the so-called 'Factory Carb'. Used by the Daytona Factory in Japan, when they built the 'Abe Bike' when they launched the Spark135 in Thailand.

Expensive.

I prefer this.

:evil: :evil:

 

[haen]

its FCR28... expensive too..and hard to rejet... (in here though due to rare jetting parts)... still i want that stock carb.. DAYTONA = EXPENSIVE...hahahaah

 

[einrennima]

traxxas,this is the TMR MJN 28

 

[einrennima]

i juz done some research on types of racing carbs...
it seems that carbs are TM 28-1,TMR MJN and FCR MJN...
is FCR MJN has TPS and ACC PUMP??

 

[haen]

good findings einrennima.. how much is that TMR-MJN 28 ?
so far the most common used carbs in my country according to usage category :

sorted from the most expensive to the 'cheapest'

RACE : FCR (Keihin) / TMR (Mikuni), TM series

STREET : PWK (Keihin) / TM (Mikuni) , PWL, PE (Keihin)

the one i look for is that carb which has TPS.. no accel pump is fine.. because sometimes it prevents good atomization.. but now I prefer PWK.. offering the best bang for the buck...

Emm..so what is the perfect carb that has tps + acc pump that can plug and play??

Any tips on lay standard card to bigger size.. beside lay bigger, any thigs to change? better performace?

 

[thrasher]

how bad does a pe28mm keihin sucks up your petrol compared to a tm24mm carb? anyone tried that before? any reviews?

 

[lc-motospeed]

i'm usind keihin 36mm carb... izzit 2 big?

 

[thrasher]

36mm?~! how the heck u fit it in there>~? care to show a pic?! i bet it drinks up petrol like no tomorrow!

 

[lc-motospeed]

petrol, not really a prob, a full tank can last me 2-3 days based on my daily usage(juz hanging around riding n sometimes pulling the throttle 2 test my bike)... the pic i'll post it some other time, bike currently in workshop coz a starting prob

TMR MJN28 is about RM1600...so ur prefer any carb that have TPS,right?
How come ACC PUMP could prevent good atomization? :roll:

 

[haen]

acc pump mechanism is squirting unatomized fuel to the chamber.. it only helps when the main jet setting is correct.. sometimes its so hard to find the correct jet size with the accel pump attached.. if the acc pump has its own setting then we'll dont have to worry much..

 

[traxxas-modifier]

if the acc pump has its own setting then we'll dont have to worry much..

just like TM28-1 and TMRMJN 28 and Keihin FCR 28mm
they have their own settings for the accelerator pump
so you can change the amount of fuel squirted.

wah,i didn't know that TMRMJN 28 and Keihin FCR 28mm has acc pump...
well i think its gonna be a problem if we're gonna use TM28-1 or Keihin FCR 28mm because have to find their suitable air filter...but for TMRMJN 28,yoshimura has those cone air filters...
right guys??

for airfilters you can buy k&N air filter for those carbs
just measure the size of the intake

i make modification at cuprix workshop ... there alot of performance carb .. they got tmr mikuni 28mm ,yoshi tm mjn 24,26mm,tmr mjn yoshi 28mm ..fcr downdraf 28mm that all performance crab ..tmr mikuni dont have tps it got power jet or acc fuel same like yoshi tmr mjn and fcr..like the mechanic told me the performance carb not recommended for daily use and i so hard to setting ..mostly this carb got borg at low rpm..working mid and high rpm..is big when u try to insttal it at ur 135 XD.... i got keihin pj 34mm sudco tune.. guees what?cant tune it until now ahaha its sux when u go low rpm.. now i use mikuni 32mm (tzm carb ).. i recommended u all use this crab.. trust me the best..low-mid-top ..petrol saving..power.. good acceleration... or can try PWK28 or uma 28mm got power jet.. tm28 also good.. if u want speed use the round slide..^^

 

[wpt4205]

so what type of carb that suitable to use (aftermarket) if we travel 166KM a day, that fit to ori carb location i actually don't mind about the petrol consumption because i'm a speed junkie hahhahahaha.....peace no war

 

[kid]

if ur bike mod so u can try PWL 28mm or PE28mm ..but use it ori ver.. mikuni 32mm still ok like i use.. but if u use performance carb like PWK or TM ..for long ride.. not recommended .. that my workshop said.. they said better find round slide carb.. for long ride ..
