Best engine mod on a Honda z50?

[quest4jest]

Ok folks . I've got a z50j that needs to be quicker , was thinking of an 88cc barrel or a chinky engine . would prefer to keep it jap engined but need to know the pros n cons , even the chinky engine do i go bullet proof 110 or a 140 for whats probarbly not much gain ,but alot more cost, given the honda is heavier than a chinese monkey (steel mudguards etc). thoughts n feelings etc please !

Jap motor any day if u r prepared to spend some serious coin,Second option would be a lifan 140 or a gpx125

GPX 125 would be a good choice i think, and not a bad time to buy either as they are on special at the moment from DHZ

New 2010 GPX 125CC RACE ENGINE, HIGH COMP PISTON, RACE CAM. One of the quickest 125cc Engine on the Market - DHZ Mini Moto

88 kit would be great if u want to keep it jap takagawa kit with performance cam?

 

[Honda 88]

I went tb 88 racehead kit on my 50 and very happy with it but if I did it again IDE go tb 108cc kit 24mm carb

 

[quest4jest]

wouldn't want to do any mods on my engine that couldn't be reversed tbh so i think the 108 is probs a no go , we don't get the gpx engine here we get the yx n other odds n sods like the 110 3 valve , I did run a 110 road legal pit for a while and found it just as quiick as the 125 . but i think this might be an 88cc with high lift cam n 20mil carb , already have a really nice jap pipe on the bike . just got to worry about the clutch taking the extra power !

If you are going the 88 route I would buy a hd clutch , and for the road I'd change it to 4 speed

 

[mini mullisha]

yer get the HD clutch its a must for over 88cc

 

[quest4jest]

The engine used to have an 88 before i owned it on it I'm just hoping the clutch and cam have been changed already . will find out when i start stripping it down for the barrel change

I've ridden Zed's with every thing from stock to way over 200cc, and love the YX 90, fir side streets and goofing. 4 speed, HD clutch and oil pump all stock. Honda clutch cover and later Honda stator cover swap right on. They're $215 over here, can't be much worse there. 107-114 upgrades are a quick bolt-on.



Or,,, you can source 85cc barrels marked 49cc, if wanting the stealth look. Splitting the cases for a 4 speed and stroker ain't the end of the world, and sure gets out of the way of the garbage truck more surely

Has anyone used web!ke for parts? they seem to be good on their bore up kits .Search Results : Motorcycle Parts & Accessories from Japan - Webike

 

[SnItChY]

yep i have used webike a few times there good , why dont ya go to monkeybike uk if your close , but stuff that all , your close to tjr in Europe , best in the game

 

[quest4jest]

tjr motorsport nice kit but £2,600 for an engine is a bit steep for me , monkeybike uk is good but almost double the price of webike , I,ve also used chells in stafford uk in the past , they are good for chinese parts and cheap too. but really want to run a honda lump in this bike so if i can build it sourcing alternative and cheaper parts suppliers then i can ride it with a bigger grin and wallet ! I was just wondering if webike was a bulk order site . Nice bike you built there snitchy

Ok finally got round to ordering an 85cc barrel and piston with the option of stroking it in to a 115cc . All parts are jap so no piston melt down or oil burning withing the first year , and i get to retain the silky smooth gearbox . I'm told it should be as quick as a 110 chinky engine at 85 cc . will be running a 20mil carb . Any thoughts or words of advice ?

 

[SnItChY]

stroke it from the outset 88's are sh!t way to slow , 4 speed box is a must , HD clutch and springs , ppl who say they are happy with there 88's are full of sh!t , im talking street riding here btw not track slappers

88 is no gutz no glory , Should have saved your coin and gone the tjr or many other European routs , but hey its yor money and bike , i know if i was that close to those tuners there is no way i would not use there skillz

best of luck tho and

To be honest,when i want a bike to hunt on then I'll buy another 1200 bandit , for the moment I'm happy with a bike to grin on, just want to catch flies at 50mph and not run out of steam up hills ! I also struggle with a honda becoming erm.... not a honda. or if you like a jap becoming chinese . yeah they look the same but there it ends . All the advice given has been and will still be gratefully recieved and taken on board but so have the videos of oil burners and lost gears . so stroke bore and a 20mil carb is on the agenda . watch this space !

thats the problem tho , an 88 at 50 mph is flat nicker and any hill will kill that speed real quick , what im trying to say is there tooooo slow with take of like a snail , but hey it aint me in front of a car at traffic lights its you

like i said ppl who say there happy with the 88 on the road are full of it , unless there like 60kgs wet , every person i know with an 88 changed em out pretty quick , be it taki or tb or china or what eva

have fun

unless you have a manual 4 speed 88 with a ported head nice aftermarket exahust and a well tuned carby setup dont bother riding it on the road as there too slow and a danger

snitchy is correct and knows his stuff
